Beyonce has launched her new campaign for Pepsi AND her new song Grown Woman.  This is interesting because it shows a definite change in how celebrities are endorsing and promoting products.  The Pepsi she drinks is incorporated into the music video, and is not some boring commercial.  Justin Timberlake did this same idea (but on a smaller scale) when he has been promoting Bud Light and his new Suit And Tie song.  Do you think this is going to be more impact-full than normal commercials?
