TV Logos

After reading Laura's post about how It's Always Sunny never changed it's logo or opening scene, I did some research on the progression of tv logos that have changed. The first article I found was of Pentagram's redesign for The Tonight Show Starring Jimmy Fallon.

The decision to go with the full moon was based on Jimmy's fresh new take on the show, creating a full circle emblem that could be used as a photographic logo or a flat image. 

The Tonight Show is one of the few shows that has a good reason to rebrand when they hire a new host. For other shows, subtle and gradual changes may work, but it probably isn't a good idea to create a completely new logo or look.
