Sony Pictures Television ID history (from the 1970s to now)

Here's an extremely rare video not related to Wheel of Fortune, and this one's about the history of Sony Pictures Television's ID's and jingles. My video starts off with the final Screen Gems TV logo of the 1970s. (Screen Gems became Columbia Pictures Television in 1974.) The ID and jingle history includes ID's and jingles for Embassy and Colex Enterprises. Sadly, the only Screen Gems ID seen here is the one with the Columbia Pictures byline (from before Screen Gems became Columbia Pictures Television).

It's on my backup Dailymotion channel for you to watch.
