Yahoo! will join Microsoft and Google, in that it is to offer video clips, in this case from two of the US's biggest cable news networks CNN and ABC News. The new service, which will go online in September of this year, will be fully integrated with Yahoo! News, and will be freely available.

The move is the latest in the continuing battle for dominance in the search market. The trick of indexing video clips from TV shows was trialled by Google video at the beginning of the year. This in itself was seen as a reaction to the launch of Yahoo Video at the end of last year.
