Clear Channel, San Antonio, Texas

Very few know that the most important radio stations in Portland, Oregon are owned by a single entity, based in San Antonio, Texas. I didn't do any research to see how customary is this in the US but to me is odd. Anyways, that wouldn't be any problem to me if the themes of the songs would not be synchronized among stations and with some people activity and even thoughts, in real time. The playlists of the past are there to prove it.
