Why are some background images blurred out in the Daredevil movie being shown on CBS?

In southern Arizona on CBS I just saw the movie Daredevil was on with Ben Affleck, and in the background of a restaurant were some products on shelves that were blurred out. I'm sure they weren't blurred out in the original movie, so why would CBS do it? They weren't in a store or anything, so I don't think the items were obscene or anything. Could they be products that are in competition with products sold by their sponsors or something? I hope that's not the reason, it seems kind of a cheap and petty reason to censor a movie. Although I can't really think of a good reason to do it.
