Hogan's Heroes was a casualty of that purge as well. The network of Edward R. Murrow could not be associated with such "lowbrow entertainment".
And here I thought Hogan’s Heroes was a victim of Bob’s peccadilloes.
As for the propaganda effect of TV, it’s there, and it’s why the rural purge occurred. Can’t have those hick programs portraying hicks in a positive light. Have to get rid of them so that we can portray the joys of ‘successful’ urban lifestyles. Out with the Clampetts, in with the Mary Tyler Moores (childless singles) and Murphy Browns (you know where that went)...
