No more corny jokes. No more dubious auto repair advice. Brothers Tom and Ray Magliozzi, the hosts of National Public Radio’s Car Talk, are hanging it up. Sort of. 

The Magliozzi brothers’ unlikely public radio career began 35 years ago with a local show on Boston’s all-volunteer WBUR that eventually caught fire and went national. While the retirement of hosts Click and Clack this October means the end of live programming for the show, there’s enough previously recorded material in the can to continue Car Talk in reruns into perpetuity.

And that would appear to be the plan. According to the Nieman Journalism Lab at Harvard University, Car Talk is far more important to National Public Radio than it might appear. With 3.3 million weekly listeners on 660 stations, the Saturday morning program is wildly popular. Weekday warhorses such as Morning Edition and All Things Considered pull in more listeners through the week, but Car Talk has the largest average audience per quarter hour. “There are more people listening at any one moment to Car Talk than to any national program,” says Anna Christopher of NPR.
