Lou Wiley, the longtime Executive Editor of FRONTLINE, has retired. Wiley worked for Boston's PBS station WGBH-TV, which produces FRONTLINE, for 33 years. He was involved in the creation of the show, along with other programming.

Of all the FRONTLINE episodes over the years, Wiley tells TVNewser he is perhaps most proud of 2000's "The Case for Innocence", produced by Ofra Bikel, which investigated cases of the wrongly-convicted. The show generated a strong public reaction.

"Ten months after the broadcast," Wiley says, "all three of the profiled prisoners had been exonerated and freed as a result of new DNA tests. For me this was an ongoing lesson in the power of good reporting to make a real difference."

Wiley will now become a consultant and also focus on his hobbies, art and antiques.
