What about a Hershey's KISS? They are the real deal, are they not? When it comes to trademarks? The human race has been kissing since the beginning of time! lol...trademark that!
Funny. But you can't trademark a word, or even a name for use in everything. For example, if I wanted to open McDonald's Dry Cleaning, I doubt I'd have any problems. But if I wanted to open an independent McDonald's fast food outlet, an army of lawyers would descend on me so fast, I'd be closed down within a few days.
Actually, I've heard a similar story. A few years ago, Burger King found out about a hamburger stand in a small town using their name. Problem is, the stand had been using the name "Burger King" since the late 40s or early 50s, way before the nationwide brand existed. Nevertheless, BK (more accurately, whatever corporation owned them at the time...Pepsico, I think) owned the trademark and the small hamburger stand ultimately had to change their name.
So like I said,
if CC actually owns the "Kiss-FM" trademark, they could probably make a legal issue out of it, but it would cost them money they probably they probably don't want to afford now - for very little return on investment. What would be the point? So they can have a "Kiss FM" in San Antonio and a few other cities? CC has much bigger problems.
