I know no one other than me is interested in these old NFL games on YouTube - I'm currently watching a Buccaneers/Falcons game from 1979, which has me questioning my own sanity - but there's a lot of cultural detritus to be found in these telecasts, especially if you're fortunate enough to find one with all the commercials intact. It's a real window into what the 1970s were really like, much moreso than, say, listening to Steely Dan's Pretzel Logic. Or into what my 1970s were like, anyway.
For instance, in the early 1970s, did you know that there were still a lot of cigar ads on TV? If you wanted to give someone White Owls for Christmas, there was an ad giving you your range of possibilities. There was even the occasional spot for pipe tobacco. You don't see that much anymore.
Even within the broadcasts, there are all sorts of great little nuggets. I've seen CBS games from consecutive weeks in 1979, and they're pimping pretty hard the "Battle of the NFL Cheerleaders," to be seen on the upcoming Saturday's CBS Sports Spectacular. I haven't seen it, but I'm assuming this battle was fought with poleaxes and maces, World of Warcraft-style.
At one point, there's a graphic showing the evening's CBS lineup, including The Jefferson's [sic], which is only slightly less embarrassing than the fact that that series was preceded by Alice, surely the worst sitcom ever produced in the free world. C'mon, guys, don't you know how to use an apostrophe? Tiffany Network, my left buttcheek.
It was much better when they promoed the Monday lineup, and erstwhile Golden Boy Paul Hornung squeals, with obvious delight, "Then it's my man, Dr. Johnny Fever! On WKRP in Cincinnati!" BOOGER!
