I don't understand whey there is always talk on this board about WPHT or KYW changing format. in 2015 the only AM stations that survive, seem to be the stations that have heritage, and stick to that heritage. Think of AM radio stations jumbo jets, that had a succesfull, 90-something year run, but they are almost out of fuel, loosing altitude, and will soon hit the ground. Most of them have hit the ground already. The ones who have not yet crashed into the ground, are gliding on their heritage. If you mess with that heritage, you will just chase off the listeners you have, and guess what, new listeners do NOT suddenly start listening to AM. Especially anyone under the age of 50. KY & PHT need to keep doing what they do, and do it well, until the asphalt starts to take the paint off the bottom of the plane!
