The Paley Center for Media dug up this interview with Jon Stewart from their archives, back when he was hosting "The Jon Stewart Show." That talk show, which started on MTV but was later syndicated, was a precursor for "The Daily Show" in many ways: He emphasized interviewing subjects he found fascinating, and actively eschewed the typical talk show format in ways that would later transform the landscape on Comedy Central.
Ron Simon, the longtime Paley Center curator, interviewed Stewart back when the comedian was all of 32 years old, and suspects that it was one of the first times (if not the first time) that Stewart had been interviewed seriously and extensively about his craft. Check out the clip above to see the interview with Stewart, as well as some of his his writing staff, which included Jimmy Fallon's future sidekick Steve Higgins.
