Most technology facts lists are trivia. A number, a date, a surprising statistic, then nothing. No explanation of why it matters or what it means.
This list is different. Every fact below comes with context. Because a fact without context is just a number, and numbers alone do not tell you anything worth knowing.
Facts About the Internet
1. Over 5.5 billion people use the internet in 2026. That is roughly 67% of the world’s population. In 2000, it was 400 million. The internet reached more than half the world’s population faster than any communication technology in history.
2. The first website is still live. Tim Berners-Lee published the world’s first website on August 6, 1991 at info.cern.ch. It explained what the World Wide Web was. You can still visit it. It is a plain text page with no images.
3. There are approximately 1.1 billion websites but only around 200 million are active. The other 900 million are parked domains, expired sites, and abandoned projects. Most of what exists on the internet is unused.
4. Google processes approximately 8.5 billion searches per day. That is 99,000 searches every second. Each search is handled by around 1,000 computers working in parallel and returns results in under 0.2 seconds.
5. More than 2.5 quintillion bytes of data are created every day. A quintillion is a billion billion. 90% of all data in existence was created in the last two years. The rate of data creation is accelerating, not stabilising.
6. The physical weight of the internet is approximately 50 grams. Physicist Russell Seitz calculated this by estimating the total mass of electrons in motion carrying internet data at any given moment. The entire internet weighs about the same as a strawberry.
7. Global internet traffic reached 5 zettabytes per year by 2025. One zettabyte is one billion terabytes. To put that in context: if you stacked every DVD ever made, you would reach the moon and back several times. 5 zettabytes is the amount of data flowing across the internet annually.
8. Wi-Fi was developed from radio astronomy research. The technology behind Wi-Fi was developed by Australian scientist John O’Sullivan while trying to detect mini black holes. The mathematical tools he used for that experiment turned out to solve the problem of wireless data transmission. He was not trying to invent Wi-Fi.
Facts About Computers and Hardware
9. The first computer bug was a real insect. In September 1947, engineers working on the Harvard Mark II found the machine was malfunctioning because a moth had been trapped in a relay. They taped the moth into the logbook with the note “first actual case of bug being found.” The word “bug” was already used informally for technical problems before this, but the moth entry is what gave the story its legs.
10. The first computer mouse was made of wood. Douglas Engelbart invented the computer mouse in 1964 at Stanford Research Institute. The prototype was a rectangular wooden block with two metal wheels. It had a single button. The cord came out of the back, which is why someone called it a mouse. The name stuck.
11. The Apollo 11 guidance computer had less processing power than a modern USB charger. The Apollo Guidance Computer operated at 0.043 MHz with 64 kilobytes of memory. A typical USB phone charger contains a microcontroller with more processing power. The engineers who landed humans on the moon in 1969 did it with hardware that would be outperformed by the chip in a birthday card that plays music.
12. The computational power of supercomputers increased by roughly 340,000 times between 1998 and 2021. In 1998, the most powerful supercomputer, ASCI Red, performed 1.3 trillion calculations per second. By 2021, the fastest supercomputer, Japan’s Fugaku, performed 442 petaflops, or 442,000 trillion calculations per second.
13. The US Air Force built a supercomputer from 1,760 PlayStation 3 consoles in 2010. The Condor Cluster was built by the Air Force Research Laboratory because the PS3’s Cell processor was exceptionally efficient for the type of calculations needed. The total cost was $2 million, far cheaper than a comparable purpose-built system. Sony’s games console was genuinely better value than specialist computing hardware for this specific task.
14. A gram of DNA could theoretically store 215 petabytes of data. That is 215 million gigabytes in a space smaller than a grain of salt. Researchers have successfully encoded text, images, and video into DNA sequences. DNA storage is not yet practical at scale but the theoretical density makes every other storage medium look wasteful by comparison.
15. The first hard drive, released by IBM in 1956, weighed over a ton and stored 5 megabytes. The IBM 305 RAMAC required a fork-lift to move and cost the equivalent of $30,000 per month to rent. A modern microSD card the size of a fingernail stores 1 terabyte, which is 200,000 times more data, weighs a fraction of a gram, and costs around $50.
16. The world’s fastest internet connection reaches 178 terabits per second. That is fast enough to download the entire Netflix library in under a second. This speed was achieved in a lab experiment using existing fibre optic cables. The average household broadband speed is approximately 100 megabits per second, about 1.8 million times slower.
Facts About Money and Technology
17. Only about 8% of global money exists as physical cash. The rest exists as digital entries in bank ledgers. When you spend on a card, transfer between accounts, or pay online, you are moving numbers in databases. The physical banknotes and coins that most people think of as “money” represent a tiny fraction of what actually exists.
18. GPS costs $2 million per day to operate and is free to use. The US government runs the GPS satellite network at its own expense and provides the signal free to anyone with a receiver anywhere in the world. The system was built for military use but civilian access was enabled in 1983 after a Korean Air Lines flight was shot down after straying off course. Every navigation app you use is running on a $2 million per day US military infrastructure.
19. Google was almost sold to Excite for $1 million in 1999. Larry Page offered to sell Google to Excite CEO George Bell for $1 million. Bell declined. He reportedly felt that if Google’s search was too good, users would find what they needed and leave Excite’s portal too quickly. Google’s current market capitalisation is over $2 trillion. Excite no longer exists as a significant business.
20. Amazon started as an online bookstore run from a garage. Jeff Bezos chose books because they had standardised formats, were easy to ship, and had a clear catalogue. His original business plan projected first-year sales of $74,000. Amazon generated $86,000 in sales in its first month. The original garage in Bellevue, Washington is now a historic landmark.
21. Microsoft’s original name was Micro-Soft. Bill Gates and Paul Allen registered the name Micro-Soft (hyphenated) when they incorporated in New Mexico in 1975. The hyphen was dropped in 1976. Gates was 19 when he dropped out of Harvard to start the company. He has said he was always confident he could go back if the business did not work out.
22. The technology industry is worth approximately $5.6 trillion in the US alone. It represents roughly 10% of US GDP. The global technology market was valued at approximately $8.3 trillion in 2021 and is expected to reach $13.8 trillion by 2026. No industry has grown faster or more consistently over the past three decades.
Facts About Phones and Communication
23. The average person opens their smartphone 150 times per day. That is once every six and a half minutes during waking hours. People read 10% slower from screens than from paper. They also blink about three times less often when looking at screens, which is why eyes feel dry and tired after extended screen use.
24. The first text message was sent on December 3, 1992. It said “Merry Christmas.” It was sent from a computer to a Vodafone mobile phone by engineer Neil Papworth because mobile phones could not yet send texts to each other. The recipient was Vodafone director Richard Jarvis. Papworth did not receive a reply because Jarvis’s phone also could not send texts yet.
25. More people in the world have mobile phones than have access to clean water. There are approximately 7.2 billion mobile phone subscriptions globally. Around 2 billion people lack access to safely managed drinking water. This is not a statement about priorities: mobile infrastructure is cheaper to build than water infrastructure in many regions, and phones are subsidised by carriers in ways that water systems are not.
26. The first commercial mobile phone cost $3,995 in 1983. The Motorola DynaTAC 8000X weighed 790 grams, measured 33 centimetres tall, offered 30 minutes of talk time, and took 10 hours to charge. It was not a product for ordinary consumers. It was a status symbol for executives. The Nokia 3210 in 1999 sold for under £100 and reached 160 million people. The price fell 97% in 16 years.
27. Monaco has more mobile phones than people. Monaco has a mobile phone penetration rate above 100%, meaning there are more active SIM cards than residents. Several countries have achieved this because people carry multiple phones or have multiple SIMs for different networks or purposes.
28. The concept of the selfie dates to 1839. Robert Cornelius took the first self-portrait photograph in Philadelphia in October 1839 using a daguerreotype process. He stood in front of the camera, removed the lens cap, ran into frame, and stood still for over a minute while the exposure was made. He wrote on the back “The first light picture ever taken. 1839.” The word “selfie” entered the Oxford English Dictionary in 2013 but the act is 187 years old.
Facts About AI and Software
29. ChatGPT reached 100 million users faster than any product in history. It reached 100 million monthly active users in approximately two months after launch. TikTok took nine months. Instagram took two and a half years. The iPhone took years. No consumer product has been adopted at this speed before.
30. 51% of code on GitHub was AI-generated or substantially AI-assisted by early 2026. This does not mean half of all software is written by AI. It means AI tools are now involved in the majority of code being committed to the world’s largest code repository. Human developers write the other half and review all of it.
31. The first computer virus was created as an experiment in 1983. Fred Cohen created the first self-replicating computer program at the University of Southern California to demonstrate a theoretical concept. It was contained in a controlled environment. He estimated it took him eight hours to write. Modern ransomware attacks cost organisations billions of dollars annually and take far longer to clean up than they took to create.
32. There are approximately 700 programming languages in existence. Most software in production is written in fewer than 20 of them. Python, JavaScript, Java, C, C++, and SQL account for the vast majority of working code. The other 680-odd languages exist for specific purposes, academic research, or historical interest.
33. The first email was sent in 1971. Ray Tomlinson sent the first email between two computers at ARPANET. He chose the @ symbol to separate the user name from the computer name, creating the format still used 55 years later. He has said he cannot remember what the first message said. He thinks it was something like “QWERTYUIOP.”
34. Technical information doubles approximately every two years. This means that if you complete a four-year technology degree, roughly half of the specific technical information you learned in year one is outdated by graduation. The fundamentals remain valid. The specific tools, languages, and frameworks change faster than any curriculum can track.

Facts About Scale and Energy
35. Google uses approximately 15 terawatt-hours of electricity per year. That is roughly twice the annual electricity consumption of the city of San Francisco. Almost all of it powers Google’s data centres. Google has committed to running on 24/7 carbon-free energy by 2030 and currently claims to match 100% of its electricity use with renewable energy purchases.
36. Training a large AI model can consume as much energy as five cars over their lifetimes. A 2019 University of Massachusetts study found that training a large NLP model produced approximately 626,000 pounds of CO2 equivalent. The energy cost of AI training is a significant and growing concern. The largest frontier models trained in 2025-2026 are estimated to consume orders of magnitude more energy than the 2019 figure.
37. There are approximately 10,000 data centres in the world. The US hosts 5,427 of them, more than any other country. Data centres now consume approximately 1-2% of global electricity. By 2030, with AI workloads, data centre electricity consumption is projected to reach 8% of global usage.
38. A single Google search uses approximately 0.3 watt-hours of electricity. At 8.5 billion searches per day, Google’s search function alone uses approximately 2.5 million watt-hours per day. The company processes your search query across multiple data centres simultaneously to achieve the 0.2-second response time, and the energy cost of that speed is real.
Facts About Security
39. “123456” is consistently the most common password in the world. It appears in data breaches hundreds of millions of times. “password,” “123456789,” and “qwerty” follow closely. Security researchers estimate that over 80% of successful data breaches involve compromised or weak passwords. The most secure commonly available authentication method, hardware security keys, is used by less than 1% of internet users.
40. The most common cybersecurity vulnerability is human error. 95% of cybersecurity breaches involve human error as a contributing factor. Phishing emails, weak passwords, unpatched software, and misconfigured systems cause more breaches than sophisticated technical attacks. The most advanced security infrastructure in the world can be bypassed if one employee clicks the wrong link. For more on this, see our Human Factor in Cybersecurity guide.
41. Cybercrime costs the global economy approximately $8 trillion per year. That makes it the third largest economy in the world if it were a country, behind only the US and China. The figure includes direct theft, ransomware payments, the cost of recovery, lost productivity, and reputational damage. It is growing at approximately 15% per year.
42. The credit card chip was invented in 1986. EMV chip technology, now standard on almost every payment card in the world, was first implemented in France in 1986. The US did not mandate chip cards until 2015, nearly 30 years later. Card fraud dropped significantly in every country that implemented chips. Countries that delayed saw higher rates of card fraud than countries that moved early.
Facts About Gaming and Entertainment
43. The gaming industry generates more revenue than film and music combined. The global video game market reached approximately $200 billion in 2025. The global film box office generates around $40 billion in a good year. The recorded music industry generates around $30 billion. Gaming is not a niche entertainment medium. It is the largest entertainment industry in the world.
44. Netflix started as a DVD-by-mail service in 1997. Founders Reed Hastings and Marc Randolph were inspired partly by a $40 late fee Hastings paid on a VHS rental of Apollo 13. They launched a website where you could order DVDs by mail and return them with no late fees. Netflix did not start streaming until 2007, ten years after its founding. The streaming service that now has over 300 million subscribers began as a postal business.
45. The Sega Dreamcast was the first console to offer online gaming in 1999. The Dreamcast included a built-in modem and launched with online multiplayer capabilities. The infrastructure was ahead of what home internet connections could support at the time. The console failed commercially for other reasons but the online gaming model it pioneered is now the standard for every major console platform.
46. The barcode was invented in 1952 but not used commercially until 1974. Norman Joseph Woodland received a patent for the barcode in October 1952. The first commercial barcode scanner was installed at a Marsh Supermarket in Troy, Ohio in 1974. The first item scanned was a 10-pack of Wrigley’s Juicy Fruit chewing gum. The gum is in the Smithsonian Institution’s collection of historically significant objects.
Facts About Space and Advanced Technology
47. SpaceX has reduced the cost of launching a kilogram of payload to orbit from $54,000 to around $2,700. In the early 2000s, launching cargo to orbit cost approximately $54,000 per kilogram on a traditional rocket. SpaceX’s reusable Falcon 9 brought this to around $2,700 per kilogram. Starship is targeting costs below $100 per kilogram. The economics of access to space are changing faster than any previous era in the space industry.
48. Quantum computers have demonstrated error correction that actually improves with scale. For decades, quantum computers had a fundamental scaling problem: adding more qubits added more errors. Google and IBM demonstrated in 2024-2025 that with the right error correction approaches, adding more qubits can reduce errors rather than increase them. This is the theoretical barrier that had to be broken before large, stable quantum computers become possible. Useful quantum computers for most applications are still estimated to be 5-10 years away.
49. The James Webb Space Telescope can see light from 13.6 billion years ago. Light travels at approximately 300,000 kilometres per second. Light that left a galaxy 13.6 billion years ago is only arriving at Earth now. When Webb captures an image of a distant galaxy, it is photographing that galaxy as it existed 13.6 billion years ago. The telescope is looking back in time as well as across space.
50. There are approximately 9,000 satellites currently in orbit around Earth. SpaceX’s Starlink constellation alone accounts for over 6,000 of them. The number has tripled since 2019. The density of objects in low Earth orbit is now a genuine concern for collision risk and for astronomical observation, as satellites create streaks across telescope images.
Facts About How Technology Changes Behaviour
51. People read 10% slower from screens than from paper. Studies consistently find that reading speed and comprehension are slightly lower from digital screens than from printed text. The effect is not large enough to prevent screen reading but it is real and reproducible. Theories include the different lighting of backlit screens, the tendency to scroll rather than read linearly, and different physical postures adopted when reading on devices.
52. The average person spends between 4 and 11 hours per day looking at screens. The range reflects significant differences by age, occupation, and country. Knowledge workers in developed countries are at the high end. Screen time has increased consistently since smartphones became widespread in the early 2010s and accelerated during and after the COVID-19 pandemic.
53. Fake Apple Stores exist in China that are so convincing the employees think they work for Apple. Multiple unauthorized stores have been found in China selling genuine Apple products in stores designed to look exactly like official Apple retail outlets, complete with staff wearing Apple uniforms. The stores obtained real products through unofficial channels. Several have been shut down; others opened elsewhere.
54. Over 90% of the world’s data was created in the last two years. This fact was true in 2020, and it remains true in 2026 because the rate of data creation keeps accelerating. The statement will likely still be true in 2030. Each generation of connected devices, sensors, AI systems, and digital communications creates more data than everything before it combined.
Six Facts That Sound Wrong But Are True
55. QWERTY keyboard layout is often wrongly described as designed to slow typists down. The QWERTY layout was designed in 1873 for the Sholes and Glidden typewriter. Common keys were deliberately separated to prevent the mechanical arms from jamming, which in practice let people type faster and more reliably by avoiding jams, not slower.
56. The @ symbol existed for centuries before email. The @ symbol appears in a 1536 Florentine merchant’s letter, used as a unit of measurement for amphoras of wine. It was used in accounting and commerce for hundreds of years before Ray Tomlinson chose it for email addresses in 1971. Every email address uses a symbol from Renaissance-era Italian commerce.
57. Finland declared broadband internet access a legal right in 2010. Finland was the first country to make broadband internet access a legal right, requiring providers to offer at least 1 megabit per second connection to every resident. The law reflected a recognition that internet access had become as essential to participation in modern society as access to electricity or telephone service.
58. The original domain for Google was “Backrub.com.” Before Google existed, the project was called Backrub because it analysed the web’s backlinks (links pointing to a page) to determine importance. When Page and Brin decided to rename it, they chose “Googol” (the mathematical term for 10 to the power of 100) but misspelled it as “Google” when registering the domain. The misspelling became the brand.
59. There are more possible iterations of a game of chess than atoms in the observable universe. The number of possible chess games is estimated at 10 to the power of 120. The number of atoms in the observable universe is estimated at 10 to the power of 80. This is why chess-playing AI is genuinely impressive: it is not searching every possible game. It is using pattern recognition and evaluation functions to navigate a space of possibilities that is physically impossible to enumerate.
60. The first computer program was written by a woman in 1843. Ada Lovelace wrote what is considered the first algorithm intended to be processed by a machine in 1843, for Charles Babbage’s proposed Analytical Engine. She recognised that the machine could do more than calculate numbers and could be used for any symbolic manipulation. The engine was never built in her lifetime. Her algorithm was never run. She died at 36. The US Department of Defense named a programming language Ada in her honour in 1980.
