Going, Going, Gone: The Return of the Remote Sports Broadcast

In a normal time, Fox announcer Mike Joy would be standing in the booth at Darlington Raceway this weekend, his eyes focused on the track. The monitor below him might show the race leaders. But Joy’s eyes would be gliding clockwise around turns 4 and 3, then sweeping across the backstretch, before bending right at Turn 2. If Joy picked out an anomaly—a puff of smoke, a car contacting another—he would say, “Crash!” or “Trouble!” For NASCAR viewers, the effect is subtle yet important. Joy is showing them something before they see it with their own eyes.
When NASCAR returns to Fox on Sunday, Joy won’t be in the booth at Darlington.
