Because Fresh in NYC is doing so well? Welcome to bland radio!
Fresh is just a name; the actual format, use of jocks, music list and focus, is different in each of the few markets the name is being used in. An LA Fresh might be radically different from the currently existing Easter ones.
In any case, we have to remember that each company has a repertoire of very few names it can use for stations so we will be seeing more and more cases of very different formats with the same name across the country due to service mark limitations caused by the Internet making every station have a presence in every city and state!
