Vevo, the online music video website powered by YouTube and major labels like Universal Music Group (UMG), has officially launched. The site currently contains 14,675 videos from 5,191 artists spread across more than 20 genres. Users are gradually taking to the site, with over 800 playlists already created.

YouTube and UMG first announced plans for Vevo in April, and the site has since gained other labels and partners including Sony Music Entertainment, EMI, AT&T, and Abu Dhabi Media Company, who contributed a reported $300 million to the project. CBS Interactive climbed aboard earlier this month, bringing with it and more than 90 CBS Radio music stations, which should be available next year.

The collaborators envision Vevo as a premium music video hub, where users can create and share playlists and more. Instead of simply distributing music videos, Vevo intends to help "sell" artists with profile pages featuring interviews and other promotional content.
