CBS Radio is upgrading all its station Web sites with video. The new capability debuts on four of its New York stations -- AC WWFS, rock WXRK, sports WFAN, news WCBS-AM -- and will roll out to others in the weeks and months ahead.

Video content will include syndicated video clips, broadcast simulcasts, live concert performances, in-studio interviews and other clips. Each participating station will be able to customize the video player and the content it carriers.

CBS tapped web video firm WorldNow to power the video platform.
