Here's one of those weirdly mesmerizing 'history of a logo' videos that are a staple of a complete Youtube diet. This is the history of the 20th Century Fox logo over a 100 year period. I knew that William Fox, an independent film distributor/producer, was the originator of things somehow but I failed to even consider that there was once a 20th Century Pictures with which he merged. You'll see precisely one logo of each before the now famous fully named company appears. The only other thing of any real interest is the fact that over the course of eight decades the theme has never been played in any key other than the original B flat.
