House and Ford

I was watching House last week and during the show, one of the doctors was driving a new ford truck. As she was driving she said something like “Oh did you know that if I take a turn too fast, this Ford (whatever model it was) will tell me!” I thought it was kind of weird that they were talking about cars during a doctor show. When the show went to a commercial the first one was about that same truck! It also said that this House episode was sponsored by Ford. I guess the big name companies really do control what we see, hear and watch.
