Setting the scene
By 2005, sharing video online was difficult—files were large, formats incompatible, and hosting expensive. The idea for YouTube came from three former PayPal employees—Chad Hurley, Steve Chen, and Jawed Karim—who struggled to share videos from a dinner party. They recognized that digital cameras and broadband were becoming common, but no easy platform existed for video sharing. They founded YouTube on February 14, 2005, and developed a simple solution: users upload videos in any format, YouTube converts them to Flash video for easy streaming in browsers.
What happened
YouTube launched as a beta in May 2005, with the first video, 'Me at the zoo,' uploaded by Karim on April 23, 2005—an 18-second clip at the San Diego Zoo. The site grew rapidly through viral videos and embedding—MySpace users embedded YouTube videos on their profiles. By July 2006, YouTube was serving 100 million videos per day. In October 2006, Google acquired YouTube for $1.65 billion in stock, a massive bet on video's future. YouTube's breakthrough was making video uploading and sharing frictionless, with no technical knowledge required.
Why it still matters
YouTube democratized video publishing, creating a new generation of creators and influencers. It became the world's second-largest search engine and the primary platform for music videos, tutorials, news, and entertainment. YouTube enabled new careers—MrBeast, PewDiePie, and others built media empires. It also transformed politics, education, and culture, but created challenges with copyright infringement, extremist content, and misinformation. YouTube's recommendation algorithm, designed to maximize watch time, has been criticized for radicalizing users. The platform demonstrated that user-generated video would dominate online media and that giving everyone a broadcast channel would fundamentally change culture and politics.
Background
Google acquired the platform the next year.
