Think Tank is a discussion program that aired on Public Broadcasting Service Public television, hosted by Ben Wattenberg. Andrew Walworth was co-creator and Executive Producer. The program was a co-production of New River Media and BJW Inc. In addition to its weekly half-hour broadcast, Think Tank produced a number of special editions, including “The First Measured Century,” a three-hour documentary series, and “Heaven On Earth: The Rise and Fall of Socialism,” a three-hour documentary series on the history of socialism, based on the book of the same title by Joshua Muravchik. The series aired from 1994 to 2010. Wattenberg has expressed a hope that the series will return to the air if and when the economy improves, making more funds available for underwriting.
