And WBBM's reveal ends up showing why they kept it simple with WWJ - they had no prior commitments to anything involving linear TV as they had no news to begin with. It really was just a chance to start fresh for that station. The other stations for better or worse do have at least something recognizable.
I'll be honest, I was one of the anti-box people at the beginning, but after seeing all the variations I've kind of accepted them. They do seem very slapped together however, and need at least some retouching to make them fit the new image better (removing the double-eye in WCBS, maybe redesigning the star 11 for KTVT). All in all though CBS did great with the new look.
