When I first saw the title, I thought it was Playboy Channel or something similar.

Goodness! It's just CNN, which is broadcast in airports, hotels, waiting areas... News is pretty much universally appealing and a channel that will satisfy most patrons.

Also, I think that the TV is for the parents to watch, unless it was specifically integrated into the play area in an area for children to view. If the TV was on the wall in the "dining" area, then I doubt that kids will be watching it.

Secondly, you think that the child was being exposed to sex and murder, but if your child is as sheltered as you make him sound, then he most likely didn't comprehend what was happening, and if he did, I doubt that his attention span would allow him to focus on CNN for too long before his "break" was up and he was going to get back to the giant hamster tubes.
