The Internet's founder, Sir Tim Berners-Lee, has spoken about it 25 years after he created it. He said it is a force for good, but it has a negative side. He told the BBC: "Everywhere I look I see a mass of energy…and also in some places, they are using the web for organised protests." He was sad at the amount of trolling and negativity. He was shocked that normal people, "suddenly become very hateful instead of very loving".

Berners-Lee was at London's Science Museum for a new 'Information Age' exhibition. It has the server that hosted the first ever website, which still has a note on it that Berners-Lee wrote about not switching it off. Berners-Lee is a director of the World Wide Web Consortium, which looks after the Web's development. He hopes people will build more web-based tools that will help us collaborate for positive change, rather than fight.
