Did you notice in the upper right corner of the video, at 2m:12s there is a five pulse flashing white rectangle?
Here's the factoid that makes that little trivia relevant.
In the early times of network television, many affiliates would break away from the feed program to air their local advertising. Since it was done manually the network would manually send a visual signal to the local broadcaster that meant in fifteen seconds the network will broadcast its own advertising to the national affiliates whom wished to air the feed. The local affiliate could then break from the network feed to air their own local programming for precisely one minute.
Sometimes the local station would fuck up and forget to switch on to their own commercials, or worse, switch late to their own programming. That is why we so frequently saw a few seconds of the network commercials that got cut mid sentence for the corny car commercials andthat would always run beyond the return time and cause us to miss so many seconds of the program we wanted to see!
That was before the discovery that the technology could have an electronic signal embedded in the broadcast band that would automatically turn on the local affiliate's playback machines to air local adverts, and then automatically return the local affiliate's to the network upon a specifically engineered end signal. ON TIME!

Adage: 2 things are certain in life; Death & Taxes. Therefore; God & Beelzebub had a meeting to fix the problem. A mighty storm prevailed for ages until finally they ended the storm with the agreement: From now on Anyone whom chooses doesn't have to die. "Everyone wins said Beelzebub. You get an eternally grateful bunch of worshippers praying forever for lower taxes as I goad & prod them forever with higher & higher taxation."
