It certainly took a while to get going (the first websites were badly designed, slow to load and had little or no animation, let alone video content) but gradually, through the 90s, the internet's influence began to grow. By the mid-1990s, we had search engines such as Yahoo and browsers such as Internet Explorer, and net surfing was born. The first websites from big brands started to appear from about 1996.myriad stats about the Web that no-one in 1989 - not even Tim Berners-Lee - could have envisaged. Knighted 10 years ago, Sir Tim has never had a huge media profile and doesn't go in for his own PR, but his influence on our personal and professional lives is probably greater than any individual of the past 50 years. And when he speaks, his influence means that his comments are carried far and wide. He still advocates a "Web for everyone"?, one that is free and accessible to all. It's a principle that, in an increasing drive to commercialise and monetise almost every aspect of the digital world, is under threat. Sir Tim has used the 25th anniversary to ask people to suggest what they think the internet should become over the next 25 years. And, as you'd expect in 2014, he's created a #web25 hashtag for the purpose. "If we want a Web that is truly for everyone, then everyone must play a role in shaping its next 25 years," he told journos gathered at the Science Museum for a peek at the computer that started it all. He's also come to the defence of whistleblower Edward Snowden, the former CIA agent. While guest-editing Radio 4's Today programme, he said Snowden had "done the world a favour"? by helping promote a more open and transparent society. And he's called for a 'Magna Carta' for the internet that would enshrine users' rights and freedom of speech on the internet. For all those reasons, Sir Tim Berners-Lee is, hands down, our top PR influencer this week. And probably every other week for the past 25 years.
