George Alexander "Alex" Trebek (born July 22, 1940) is an Emmy Award-winning Canadian-American television personality and game show host. He has been the host of the game show Jeopardy! since September 10, 1984. He has hosted numerous game/quiz shows and has appeared in television series, usually as himself. Though a native of Canada, he became a naturalized United States citizen in 1998.

Born and raised in Sudbury, Ontario, Trebek graduated from the University of Ottawa with a degree in Philosophy. After his first decision to become a newscaster, he joined the CBC (Canadian Broadcasting Company), Canada's premier network in 1961. As he was working, he helped organize national news and covered a variety of special events for CBC's radio and television divisions, receiving high praise as a broadcaster who retained his poise and composure in the toughest places. Then, in 1966, he became a Canadian game show host on "Reach for the Top" (1965), and stayed there for the first seven years until he migrated to the United States to host his very first game show in that country, "Wizard of Odds, The" (1973), for NBC. Prior to being selected as the host of "Jeopardy!" (1984), for syndication, he came back to NBC and hosted the revamped version of "Classic Concentration" (1987), which was also his second hit in his almost 30 year career. On this show, he received 4 Emmy nominations, but didn't win. It was cancelled in 1991, when the network stopped making game show for daytime TV. On May 17, 2002, "Jeopardy!" (1984) celebrated a milestone, the show celebrated its 4000th episode and at the same time, it received another Daytime Emmy for "Outstanding Game Show/Audience Participation", making it its 21st Emmy. Like Bob Barker, Alex Trebek had broken the world record as host of TV's #1 quiz show in the country, and he won 2 Emmy Awards and received a star on the Hollywood Walk of Fame, and, this year, was described as one of the Top 10 Canadians on U.S. Television. Today, as Alex began his 19th year as the host, he remains as popular as any other quizmaster.
