WWWM

A sticker and magnet from Hot Adult Contemporary WWWM licensed to Sylvania, Ohio near Toledo.  They've been branded "Star 105" since 1998.

UPDATE:  WWWM later renamed itself "Channel 105.5" and then in the summer of 2016 switched again to "Q105.5".  The reason for their re-branding sounds like something that was written by the satirical news organization The Onion.  Here's a quote from Cumulus Media's Toledo market manager:  "Our market research showed that people really like the letters of the alphabet. More specifically, they love the letter 'Q.' It is simply a matter of giving listeners what they want with this new brand."
Are you kidding me!?  That's one of the stupidest things I've ever heard in my life (and yet, still, possibly completely true.)  I'm just trying to picture some unpaid intern doing "market research" to determine how people feel about the alphabet.  "The alphabet? I LOVE it!  Especially the letter Q!"  Ridiculous....
