I "beat the blackout" of many a Bears game in the 60s by watching them through the snow on Rockford's WREX-TV channel 13, which was a CBS affilliate in those days. Fast forward to the early 70s when I was working at WHBF-TV and radio, the CBS affilliate for the Quad Cities (Illinois-Iowa), which was on the Bears network, so we had the all the Bears games even if blacked out in Chicago.
......Well, ALMOST all of them. One Friday before the end of the season, a bunch of us were all sitting around rather bored, and one guy got the bright idea of picking up the phone, calling up CBS in New York, and asking them to flip us from a meaningless Bears game to a Packers game with playoff implications. To our astonishment, the CBS guy said, "Okay sure". When game day Sunday rolled around, the switchboard was closed, and the calls rang into the newsroom. Where I happened to be working. Suffice to say my ears are still burning.
Of course I blamed the whole episode on "Those suits at CBS".
