Time Warner plans to leverage its Warner Bros movie catalogue in a deal to release a "significant chunk" of archived television programmes through its AOL division.

Business Week reports that Warner Bros and AOL will reveal the deal to make old TV programmes available as free downloads, perhaps later today. No current shows will be made available as part of the deal.

The move follows Apple's deal to offer leading US TV shows from ABC in a format compatible with iPod video; NBC and CBS are also arranging similar distribution deals with DirecTV and Comcast respectively.

Business Week observes that the recent spate of deals signifies a "dislocation" of traditional media business models in response to new technologies.
