What a strange thread.
Who are some game show hosts that hosted more than one show on the same network?
I know that Dick Clark did the $25,000.00 Pyramid and Winning Lines for CBS.
Are we looking for only game shows? If not, an even better example for Mr. Clark is ABC Pyramid and Bandstand.
Clark, at one point, had one show on each of the (then three) networks -
Pyramid on CBS,
Bloopers and Practical Jokes on NBC, and
American Bandstand on ABC.
Going back to game show hosts, here's a few examples:
Tom Kennedy (I'm excluding stuff like A Date With the Angels and About Faces)
ABC -- Doctor I.Q., Split Second, You Don't Say, Break the Bank
CBS -- Whew!, Body Language
NBC -- The Big Game, You Don't Say, 50 Grand Slam, Name That Tune, To Say the Least, Password Plus, Body Language
Alex Trebek
ABC -- Super Jeopardy!
CBS -- Double Dare
NBC -- The Wizard of Odds, High Rollers, Battlestars, Classic Concentration, To Tell the Truth
Bill Cullen (again, host only)
ABC -- The Price Is Right, Blankety Blanks
CBS -- Give and Take, Place the Face, Name That Tune, I've Got a Secret, Pass the Buck, Child's Play
NBC -- Winner Take All, Bank on the Stars, Down You Go, The Price Is Right, Three on a Match, Winning Streak, Chain Reaction, Blockbusters, Hot Potato
You get the idea.
