In a report called Creative Future, described as an "editorial blueprint", director-general Mark Thompson outlined plans for the corporation to respond to a world in which "on-demand" entertainment rules.
He warned staff at the BBC that it risked losing a generation of younger audiences if it did not respond to changing habits.
In his speech to the Royal Television Society, Thompson said: "The BBC should no longer think of itself as a broadcaster of TV and radio and some new media on the side. We should aim to deliver public service content to our audiences in whatever media and on whatever device makes sense for them, whether they are at home or on the move."
The report recommends a number of changes in areas such as sport, news and drama.
Its news operations are to be restructured around BBC News 24, which will have key talent moving to it. The aim is to have continuous news coverage on the web, television and radio.
With regards to sport, 'Grandstand', described by the BBC as a "brand which no longer has impact", will be phased out. A BBC Sport broadband portal will help give more coverage to a diverse range of sports, and a BBC sports editor will be appointed.
The future of 'EastEnders' appears assured after the BBC said it would continue to "cherish" long-running drama series. However, it said that would aim for fewer television titles with longer runs, and experiment with drama in gaming and interactive.
Ashley Highfield, the BBC's director of new media and technology, unveiled a competition to redesign and reimagine the bbc.co.uk homepage in what the corporation is dubbing the "Web 2.0 world", to exploit the functionality of services such as Flickr, Wikipedia and YouTube.
