when did wheel of fortune get touch screens
Wheel of Fortune (U.S. game show) The show's original puzzle board had three rows of 13 manually operated trilons, for a total of 39 spaces. On December 21, 1981, a larger board with 48 trilons in four rows (11, 13, 13 and 11 trilons) was adopted. This board was surrounded by a double-arched border of lights which flashed at the beginning and end of the round. Each trilon had three sides: a green side to represent spaces not used by the puzzle, a blank side to indicate a letter that had not been revealed, and a side with a letter on it.[23] While the viewer saw a seamless transition to the next puzzle, with these older boards in segments where more than one puzzle was present, a stop-down of taping took place during which the board was wheeled offstage and the new puzzle loaded in by hand out of sight of the contestants. On February 24, 1997, the show introduced a computerized puzzle board composed of 52 touch-activated monitors in four rows (12 on the top and bottom rows, 14 in the middle two).[10] To illuminate a letter during regular gameplay, the hostess touches the right edge of the monitor to reveal it.[79] The computerized board obviated the stop-downs, allowing tapings to finish quicker at a lower cost to the production company.
Wheel of Fortune (U.S. game show) The network version was originally hosted by Chuck Woolery and Susan Stafford, with Charlie O'Donnell as its announcer. O'Donnell left in 1980 and was replaced by Jack Clark. After Clark's death in 1988, M. G. Kelly took over briefly as announcer until O'Donnell returned in 1989. O'Donnell remained on the network version until its cancellation, and continued to announce on the syndicated show until his death in 2010, when Jim Thornton succeeded him. Woolery left in 1981, and was replaced by Pat Sajak. Sajak left the network version in January 1989 to host his own late-night talk show, and was replaced on that version by Rolf Benirschke. Bob Goen replaced Benirschke when the network show moved to CBS, then remained as host until the network show was canceled altogether. Stafford left in 1982, and was replaced by Vanna White, who remained on the network show for the rest of its run. The syndicated version has been hosted continuously by Sajak and White since its inception.
