An artifact from the early days of cable:
Cable TV in Sault Ste Marie, MI, 1969: 4 whole channels! And FM! pic.twitter.com/Ow2h26TeFv

What I wanted to know is this: what four channels? Sault Ste. Marie had no TV stations of its own in 1969; WWUP-TV (UP, get it?), channel 10, rebroadcast WWTV, the CBS station in Cadillac, Michigan; WPBN-TV (then owned by the Paul Bunyan Network), channel 7, brought in NBC from Traverse City. There was no ABC affiliate back then, so those two split whatever ABC programs they thought might be worth carrying. (In 1971, WGTU, channel 29, would sign on from Traverse City as a full-time ABC affiliate; five years later they added a satellite on channel 8 in Sault Ste. Marie proper.) Educational TV? Maybe, if you could pick up WCMU-TV from Central Michigan University in Mount Pleasant — and if you were on the cable, you probably could, even though WCMU was way out on channel 14.
Still, we’ve accounted for only three channels. For the fourth, we must venture northward. In 1955, CJIC-TV signed on from the Ontario side of the river on channel 2; it became a CBC affiliate, closing down in 2002. (It’s now rebroadcasting CBC Toronto.)
As for prices, well, $3.99 a month (we’re extrapolating from “13 cents a day”) for four channels works out to about a buck a channel. Last time I rescanned the TV I was getting 106 channels for $86, 81 cents a channel. If there were economies of scale in the cable industry, they’ve long since faded away.
(I should point out here that I’ve spent maybe half a week of my life in Michigan, and none in the Upper Peninsula; I do have a lot of reference materials, and occasionally, I have time on my hands.)
