Here’s a short excerpt about an unusual TV station from Timothy Green’s The Universal Eye (1972):
“The village of Pembina in North Dakota seems a strange place to have a powerful television station. Only a couple of hundred people live there and the nearest American town of any size is many miles away. But the advertisers who queue up to buy time on KCND-TV Pembina have their eye, not on Americans, but on the half a million Canadians living just north of the border in the city of Winnipeg. The investment pays off; the people of Winnipeg spend a fifth of their viewing time watching the Pembina station.”
Eventually, KCND ended up moving from the U.S. to Canada and becoming CKND.
