In a programming first for the WB, the netlet will tackle the annual live event show format, launching “The WB Radio Music Awards” in the fall.

The announcement of the two-hour spec comes on the heels of the success of “Songs From Dawson’s Creek,” an album based on music from the WB’s eponymous series — and the No. 1 selling soundtrack in its first week out.

“We were looking for a special that would recognize the enormous impact music has had on our most distinctive television series,” WB entertainment prexy Susanne Daniels said. “This special strikes us as the ideal way to marry the two art forms.”

“The WB Radio Music Awards,” with venue, host, presenters and performers to be announced, will recognize radio-friendly musicians and bands from six genres. Favorite on-air personalities will also be feted.

Noms will be based on the amount of radio airplay given last year to groups and solo artists. Winners will be picked by a team of 400 radio programming execs.

“This will be one of the three or four major music events of the year,” said “WB Radio Music Awards” exec producer Anthony Eaton, a three-time Grammy winner for longform vids, including “Madonna: Blond Ambition World Tour.”

Other exec producers are Von Freeman, marketing director for Clear Channel Communications, and “Rick Dees Weekly Top 40” exec producer Paul Joseph.
