Four national newspapers - the Daily Mail, Daily Telegraph, Guardian and Independent - are to share BBC video news content on their websites free of charge.
The BBC said the move was the best way to sustain public-service content and is seen as a way of countering criticism from newspapers that the Corporation had stifled their attempts to expand online.
BBC media correspondent Torin Douglas said the agreement, which begins today, marked a thaw in relations between the Corporation and commercially-funded media.
Other newspaper websites could sign up later, he said.
The BBC already has a video sharing agreement with YouTube which allows the site to screen short clips of its content.
In return for sharing its material, the BBC receives a share of the advertising revenue generated by traffic to the YouTube channels.
