Happy Birthday World Wide Web!

Today, around the world, people are joining Web inventor Tim Berners-Lee in wishing the World Wide Web a happy 25th birthday. To mark the occasion, everyone is encouraged to share birthday greetings on social media using #web25. Select greetings will also be posted on a virtual birthday card on the official anniversary site.

"The Web's billions of users are what have made it great," said Berners-Lee. "I hope that many of them will join me today in celebrating this important milestone. I also hope this anniversary will spark a global conversation about our need to defend principles that have made the Web successful, and to unlock the Web's untapped potential. I believe we can build a Web that truly is for everyone: one that is accessible to all, from any device, and one that empowers all of us to achieve our dignity, rights and potential as humans."
