Radio Smart Talk for Friday, January 14: For the last five years, Mike Trinklein and his co-producer Steve Boettcher have been digging up classic clips, and interviewing "Pioneers of Television." That's the name of their public television series, which premieres its second season Tuesday night at 8, with episodes devoted to classic science fiction, westerns, crime dramas, and children's television. We'll talk with Mike about some of the pioneers his series profiles, and listen back to some classic moments from television history.
