COUNTRY MUSIC
PBS, 8:00 p.m. ET
Episode Two of Country Music, which covers the years 1933-45 and spans The Depression and WWII, shows how both movies and the radio, as one surrendered to the other as the dominant entertainment medium, helped popularize country music. The movies gave us such singing cowboys as Gene Autry, and radio gave us Roy Acuff and the Grand Ole Opry. Check local listings.
