Logorama

According to Wikipedia, the creators described the film as the presentation of “an over-marketed world” where “logotypes are used to describe an alarming universe (similar to the one that we are living in) with all the graphic signs that accompany us everyday in our lives.”
During his Oscar acceptance speech, the producer opened by thanking "the 3,000 unofficial sponsors" and assured them that "no logos were harmed in the making of the project."

Although, if you search it on YouTube, you'll see that few links remained, the other were removed "due to copyright claims".
