Strange as it may seem, with the competition between networks, I have read over the years of a handful of incidents where a program was broadcast on more than one network simultaneously. I'm not talking about news events (like, say, a Presidential inauguration or speech), but actual scheduled special programming that aired on multiple networks at the same time. (Also not referring to U.S.-based shows that might occasionally have been scheduled at the same clock time in the U.S. and in Canada.)
The only two that come to my recollection are the first Super Bowl (which was carried by both NBC and CBS, though I'm not sure if they used separate announcers or cameras) and the well-known special "Cartoon All-Stars to the Rescue," which was shown on all the broadcast networks and a handful of cable channels at the same time. My addled middle-aged brain tells me that I have read of a few other such cases over the years, but I'm damned if I can recall what they were. You students and aficionados of broadcast history, come to my rescue.
(TRIVIA NOTE: What was significant about the use of the characters Bugs Bunny and Daffy Duck in "Cartoon All-Stars to the Rescue?" Answer: it was the first time those classic Looney Tunes characters were voiced by someone other than Mel Blanc, who had died shortly before the special was produced. Bonus points if you can tell me who did the voices without looking it up on IMDB or another web source...)
