The founders of video-sharing website YouTube have purchased the bookmarking service Delicious, from Yahoo.

Chad Hurley and Steve Chen sold YouTube to Google Inc. for $1.65bn (£883m) in November 2006.  They will use Delicious as a key part of their next online venture, named Avos.

The price of this purchase has not been revealed.

Delicious is a social bookmarking system, allowing its users to flag and tag websites, articles and media in which they find interesting.  These are then shared with other Delicious users.

The social boomarking site was purchased by Yahoo in 2005.
