Winning Streak is a weekly Irish game show in which five contestants play a number of games to win cars, holidays, and cash prizes up to €500,000. Broadcast on Saturday nights between September and June on RTÉ One, the game show is among the channel's most popular programmes, often ranking among the top five in the ratings. However, there was a significant drop in viewership in the 2008/2009 series. The game show began on 21 September 1990, and has been hosted by popular television personalities Mike Murphy (1990–2002) and Derek Mooney (2002–08). Prize money for the show is funded by the Irish National Lottery, with entry to the game based on National Lottery scratchcards. The programme is noted for the unusually high amount of contestants selected from County Donegal.
Mooney stepped down as the show's host at the end of the 2007–08 season. The 2008–09 season was rebranded Winning Streak: Dream Ticket and was co-hosted by Kathryn Thomas and Aidan Power. They were the first duo to host the programme and Thomas was the show's first permanent female presenter. Aidan Power stood down, after the 2008/09 season ended on 6 June 2009, because of his commitments to the RTÉ Young Peoples Programme The Cafe, as well as presenting on The All Ireland Talent Show in early 2010. Marty Whelan stepped into Aidan's shoes, co-hosting the 2009/10 series with Kathryn, which aired from 12 September 2009 (reverting to its original name Winning Streak) until 29 May 2010. The current series, now in its twenty-first season, commenced on 4 September 2010, again with Kathryn Thomas and Marty Whelan at the helm. Kathryn was then replaced with Geri Maye.
