The Biography Channel will be running a bunch of Las Vegas related shows on August 18, 19 & 20. Some of the subjects/titles are: The Rat Pack; Las Vegas-Gamble in the Desert; Las Vegas-House of Cards; Casino Technology; Las Vegas After Dark; Wayne Newton; Liberace; David Copperfield.
Some of these titles sound suspiciously familiar, so they may just be reruns of shows that have been around a while.
