In 2004, B94 was my station. The dial was set and I'd never turn to KISS or anything else for Today's Hit Music. I'm glad the B is back, but times have changed. Now when I'm in the car, I'll flip back and forth between KISS and B to find a good song. Music is also easily accessible through the internet and iTunes. B94 is no longer as important to me as it once was in the 90s and early 00s.
I think they should stick with the format. Nothing else has worked. Give it time to grow. If they try anything else at this point, the ratings are going to tank even lower than they are now! This has been proven with K-Flop and The Zone.
