Who is Henry Winkler

Jumping the shark is a colloquialism used by TV critics and fans to denote the point in a television program's history where the plot spins off into absurd story lines or unlikely characterizations. These changes are sometimes the result of efforts to revive interest in a show whose viewership has begun to decline. In other cases, the changes have other causes (e.g. an actor quitting, different writers being hired) and the diminished interest is the result. The two causes can feed into each other, leading to even greater changes and even lower popularity. Nonetheless, some series remain profitable and popular long after they have been judged by some to have "jumped the shark". The phrase has recently come into more general usage, and is applied to cultural phenomena other than television programs.

MacGyver was an American action/adventure television series created by Lee David Zlotoff and executively produced by Henry Winkler and John Rich that aired on ABC. Seven seasons were produced, all of which were broadcast by the ABC Network in the United States and various other networks abroad from 1985 to 1992. The series was filmed in Los Angeles during Seasons 1, 2 and 7, and in Vancouver, Canada from Seasons 3-6. The show's final episode aired on May 21, 1992 on ABC.

The story arc of MacGyver follows the laid-back, extremely resourceful secret agent Angus MacGyver, played by Richard Dean Anderson. He prefers non-violent conflict resolution wherever possible and refuses to carry or use a gun. MacGyver works as a problem solver for the fictional Phoenix Foundation in Los Angeles. Educated as a scientist with a background as a Bomb Disposal Technician/EOD in Vietnam ("Countdown"), and from a fictional United States government agency, the Department of External Services (DXS), he is used as a resourceful agent able to solve a range of problems along with his ever-present Swiss army knife.

The series was a ratings success for ABC and was particularly popular in the United States, Europe, Australia and New Zealand. The series received much critical response, and MacGyver was honored with numerous awards and award nominations in its seven-season run. Two television movies, entitled Category: MacGyver: Lost Treasure of Atlantis - and Category: MacGyver: Trail to Doomsday - , aired on ABC in 1994. While never released, a spin off entitled Young MacGyver was planned in 2003. A live-action feature film is planned with a release date yet to be announced. Merchandise for the MacGyver media franchise includes games and toys, print media and an original audio series.
