Local radio listeners who missed the front page of Saturday’s Washington Post were in for a rude awakening this morning. WTGB 94.7 “The Globe,” D.C.’s last classic rock station, changed formats today. The station is now called 94.7 Fresh FM, and offers contemporary pop music programming like Maroon 5, Kelly Clarkson and John Mayer. The Post’s story offers an appropriate lament for the demise of classic rock and further homogenization of the local radio landscape. Apart from the overall decline in radio audiences thanks to iPods and the like, it seems classic rock stations all over the country are struggling to interest advertisers due to their aging fan base. There was just no way for WTGB to end up back in black if it stuck with AC/DC.
