Thirty years ago Tuesday, software engineer Tim Berners-Lee submitted a proposal to his boss that would set the technology world on fire and usher in the information age.

Berners-Lee was working at the European Organization for Nuclear Research (CERN) outside of Geneva, Switzerland, in 1989 when he wrote Information Management: A proposal. It was a blueprint for better managing and monitoring the flow of research at the labs, but within its pages were the underpinnings for what would become known as the World Wide Web.

Google, which was made possible by Berners-Lee’s invention, on Tuesday marked the technology milestone with an animated Doodle featuring pixelated letters reminiscent of the crude, block graphics that were common on early web pages. The image of a globe slowly renders on the desktop computer’s monitor as a reminder of the slow download speeds that hobbled our experiences in prebroadband days.

The whole thing began when Berners-Lee grew frustrated that CERN was losing track of valuable project information because of personnel turnover and incompatible computers people brought with them to the office.

Berners-Lee’s proposal contained the basic concepts of the web, including ideas like HTML, URL and HTTP, but it would be another couple of years before he could demonstrate his idea. It would be another couple of years until Jim Clark and Marc Andreessen popularized the notion of commercial web browsing with Netscape in the mid-1990s.

In his annual letter on the web’s birthday, Berners-Lee on Monday expressed optimism about what can be achieved in the next three decades.

“Given how much the web has changed in the past 30 years, it would be defeatist and unimaginative to assume that the web as we know it can’t be changed for the better in the next 30,” he said.

There are nearly 2 billion websites today; serving together as a platform for socializing, shopping, gaming or watching videos online, it’s hard to imagine getting along with out it.

Happy birthday, web!
