Windows Media Player, released with Windows 3.1 on April 6, 1992, was the application through which the majority of computer users first heard digital audio. Pre-installed on every Windows PC, it dominated an entire era of personal computing.
On April 5, 1993, Jensen Huang, Chris Malachowsky, and Curtis Priem founded NVIDIA with one goal: build a dedicated chip for 3D graphics. Today, NVIDIA is one of the most valuable companies in the world, powering AI and blockchain alongside gaming.
In April 1991, AT&T sued BSD, claiming its Unix System V code had been used without permission. The three-year legal battle froze BSD development at a critical moment — and inadvertently handed Linux the window it needed to dominate.
On April 3, 1975, Bill Gates and Paul Allen registered Microsoft — originally called Micro-Soft, with a hyphen. The company started by building a BASIC interpreter for the Altair 8800, a computer they had never even touched before writing the software.
Lexis, officially presented on April 2, 1973, was one of the first computerized search systems in history. It allowed lawyers to search court decisions and statutes via terminal — at up to several hundred dollars per hour.
RFC 3514, published on April 1, 2003, proposed a radical solution to internet security: requiring attackers to mark their malicious packets with a special "Evil Bit." Several software systems later claimed they had implemented support for it.
On March 29, 1967, Texas Instruments unveiled the Cal-Tech prototype — the first electronic handheld calculator. It could add, subtract, multiply, and divide, ran on batteries, and printed results on paper tape. The main point was proving what integrated circuits could do.
In late March 1999, the Melissa virus spread from a single Usenet post to tens of millions of computers in days. It came from trusted contacts, caused $80 million in damage, and forced companies worldwide to shut down their email systems — one of the first mass internet attacks to cause real economic harm.
On March 25, 1995, Ward Cunningham launched WikiWikiWeb — the first website that let anyone edit any page directly in a browser. The web had been mostly static until that moment. This simple idea later became the foundation for Wikipedia, Confluence, Notion, and most modern collaborative documentation tools.
On March 23, 1965, NASA launched Gemini 3 — the first American spaceflight to carry a digital computer onboard. The computer couldn't make autonomous decisions, but it could calculate orbital positions faster than any human. A few years later, its descendants landed people on the Moon.
On March 22, 1965, Digital Equipment Corporation released the PDP-8 at $18,000 — dramatically cheaper than any mainframe. For the first time, universities, labs, and factories could afford their own computer. It helped move computing out of isolated rooms and into everyday work.
On March 21, 2006, Jack Dorsey posted the first tweet: "just setting up my twttr." It looked like nothing at the time. It became the starting point of microblogging — a format that changed how people share news, opinions, and reactions in real time.
In March 1970, early ARPANET engineers published RFC 36–39 — documents that read more like engineering conversations than finished standards. They are a snapshot of the internet being invented in real time, by people trying things and writing them down.
On March 19, 1997, Microsoft released Visual Studio 97 — the first version of what would later become one of the most widely used development environments in the world. It bundled Visual Basic, Visual C++, Visual FoxPro, and Visual J++ into a single package for the first time.
On March 18, 2004, security researchers reported Phatbot — an unusually advanced malware framework written in C++ with object-oriented design. It wasn't just a worm; it was a modular platform for building botnets, and it marked a turning point in how malware was designed.
Bill Atkinson was born on March 17, 1951. He created QuickDraw, MacPaint, and HyperCard — three pieces of software that defined what a graphical user interface could be. Before Atkinson and his colleagues, computers were text-based and inaccessible to most people.
Richard Stallman was born on March 16, 1953. He launched the GNU Project, founded the Free Software Foundation, and authored the GPL — the license that established copyleft and created the legal foundation for most of the open-source ecosystem we use today.
On March 15, 1985, symbolics.com became the first registered .com domain. There were no registrars, no web forms, and no fees — just an email request reviewed manually by a small team of engineers. By the end of that year, only six .com domains existed in the world.
On March 14, 1955, Bell Labs announced TRADIC — the first fully transistorized digital computer. It consumed less than 100 watts and proved that transistors could replace vacuum tubes, triggering the technological shift that eventually led to integrated circuits and modern processors.
On March 13, 1983, the Motorola DynaTAC 8000X became the first commercially available handheld mobile phone. It cost $3,995, weighed 790 grams, offered 30 minutes of talk time — and changed the idea of what a telephone could be.
