Chad Hurley and Steve Chen, the brains behind YouTube, have acquired the social bookmarking site Delicious from Yahoo, a Yahoo spokeswoman confirmed.

Delicious will become a part of Hurley and Chen’s new Internet company, AVOS, starting in July 2011. The company has been looking for someone to buy the service since December.

Yahoo and AVOS promised that the transition will be seamless. Starting today, Delicious users can log in to the service and transfer their bookmarks to the new owners.

“You’ll enjoy uninterrupted use of the service and will keep your account and all of your bookmarks when we make the transition,” Yahoo said in a statement.

On a frequently asked questions page about the transition, Delicious promised that user names, passwords, profile information, bookmarks, and other content will transfer to the new company.

In a release from AVOS, Yahoo’s John Matheny said that Yahoo chose Hurley and Chen to take over Delicious “based on their passion and unique vision” for the service.

AVOS also announced plans to build a Delicious extension for Firefox 4.
