This is so clever. Fauxgo, a tumblr, collects faux logos created for movies and tv shows. Above three from shows/movies I loved, and they all happened to play integral parts in their stories, and hence are very recognizable. Mad Men, Monsters Inc., and LOST. C
Check out the gallery for more (their titles tell you what they came from and the name of the company), and Fauxgo for even more (with more added all the time).

Love this flickr set of Mid-Century Modern logos designed in the 60s, particularly the letterform logos. So simple, and now so retro looking compared to flashy modern corporate logos, but they remind you how much personality can be conveyed in a letterform.
They also reminded me of the San Francisco MUNI logo that I spend a considerable amount of time looking at as the buses and trolley drive around town. I love that SF has stayed with this logo, which was designed in the mid-70s by a Bay Area graphic designer.
