Today marks the 25th birthday of the creation of the World Wide Web.  

The anniversary comes as more than 2.7 billion people around the world now have a connection to the web.

The web's inventor, Tim Berners Lee, has said he believes it is under sustained attack from governments and corporations.

He has called for new rules to guarantee privacy, free speech and responsible anonymity.

On March 12 1989, British computer scientist Tim Berners Lee submitted a proposal for an information management system to his bosses at the particle physics centre at CERN.

Originally designed as a means of enabling physicists to collaborate, it was described by CERN management as vague but exciting, and was initially rejected.

But the project was later given the go-ahead and the following year Berners Lee published the first web page.

It was to signal the start of an extraordinary revolution which in the following 25 years has led to vast changes in how we live our lives.

In that time whole industries including music, publishing, media and travel have been utterly transformed by the world wide web.

But it has not all been good, with the web's rise accompanied by new forms of crime and breaches of privacy.

Today there are more than 60 trillion web pages, and more than 2.7 billion users globally.

However, many experts believe most of the history of the web is ahead of us, with the technology still a long way off reaching its full potential.
