On this day in history, August 26, 1939, baseball broadcast on TV for first time

Henry Levy, 100 years old, enjoyed a dream come true recently on a New York ballfield.

The Cincinnati Reds visited the Brooklyn Dodgers and split a double-header at Ebbets Field as Major League Baseball was broadcast on television for the first time on this day in history, August 26, 1939. 

"No monitor, only two cameras at Ebbets Field," said Dodgers radio announcer Red Barber, who called the game for TV, according to the National Baseball Hall of Fame. 

"I had to watch to see which one’s red light was on, then guess its direction."

"Regular programming did not yet exist, and very few people owned television sets — there were only about 400 in the New York area," reports History.com. 

Many sets were just 5-inch models.

But the event launched what's now the multi-billion dollar industry of televised sports.
