Putting the BS in CBS and PBS

Three of my favorite TV logos.  Sometimes I play these (in this order) to soothe myself before bed:

-PBS (1970s-90s... Mr. Rogers):


-Paramount Pictures (1970s-80s... Cheers, Happy Days, Taxi; modern reruns of these shows just don't seem right without this musical sting at the end). This company is now part of CBS-TV.  How fortuitous for the next entry...


 -CBS Special (1970s-80s... Bugs Bunny, Charlie Brown):



-Here's a couple more that aren't really favorites of mine, but are just interesting...
This is Showtime's early 1980s "After Hours" intro.  You'll notice on this evening, they're showing "Confessions of a Driving School Instructor," a terrible British sex farce in the mould of early "Police Academy."  I've also seen this intro before the weak Don Adams/Don Rickles burlesque special "Two Top Bananas" (not Rickles' fault).  And judging by the graphics, this also would have been used for boxing matches? What a bizarre catch-all. Seems like this was just a way of titillating viewers into thinking they were about the get X-rated material (which wasn't even shown on the Playboy Channel back then).


-And this is the adults-only open from the Chicago-based "ON TV" system (from the days before cable television was allowed into the city).  They gave viewers a LOT of time to make sure the kids were out of the room and away from the television.  The system was transmitted via a standard broadcast signal (Channel 44), but required a de-scrambler at home, meaning it was much easier to possibly hack into than traditional cable TV (which finally came to Chicago in the mid-80s).


-This looks like the close from the same broadcast of the same film... interesting choice of short subject afterward ("A Phantasy" by Norman McLaren); the music is terrifying:
