It was 10:30 on a Sunday morning and Jack Horner was getting ready for church when his phone rang 70 years ago. The fourth of his six sons had just been born and now the 35-year-old radio sportscaster's Sunday plans were about to change.
And so was Minnesota broadcasting history that Dec. 7, 1947 — precisely six years after Japan attacked Pearl Harbor and pulled America into World War II.
"December 7 may be a 'day that will live in infamy' in the history of the United States," Horner wrote in 1962, "but it's the day of TV's first big milestone in the Twin Cities and Minnesota."
The telephone caller that morning was Jack Fricker, the chief engineer at KSTP-AM. Horner had been announcing the station's football broadcasts for three years. Fricker called to say that their boss, station owner Stanley Hubbard, wanted him to scoot down to the studio by noon.
Hubbard had purchased 20 Philco television sets — seven-inch contraptions with lift-up tops and primitive built-in projectors. He'd scattered the sets in homes across the Twin Cities — trying to get his prominent pals to embrace this embryonic new media.
Now it was time to test the technology with a local broadcast, scheduled to air at 8 p.m. It would be the first TV program produced in Minnesota.
"We knew darn well what station they would be watching," Horner recalled, "but the concern was how well was the signal received in various Twin City sections."
They had eight hours to get ready, but that time wasn't spent writing scripts or rehearsing. The small staff, summoned on a Sunday, focused on makeup.
