The BBC's TV channels will be made available on the internet, BBC Director General Mark Thompson has confirmed.

"We believe that on-demand changes the terms of the debate, indeed that it will change what we mean by the word 'broadcasting." ... An expanding portion of the BBC's audio and video material from the archive will also be able to be accessed via MyBBCPlayer. "It should make it easier for users to find the content they want whenever and wherever they want it."

He said he hoped the service would launch next year.

A simulcast of BBC One or BBC Two, letting UK viewers see programmes on the web at the same time as they go out on TV, is also planned as part of MyBBCPlayer.
