<P> This incarnation was created by Simon Cowell, and was originally due to be a 2005 British series called Paul O'Grady's Got Talent but was postponed due to O'Grady's acrimonious split with broadcaster ITV (later launching as Britain's Got Talent in 2007). Therefore, the U.S. version became the first full series of the franchise . </P> <P> The original judging panel consisted of David Hasselhoff, Brandy Norwood, and Piers Morgan . Sharon Osbourne replaced Norwood in season two (2007), and Howie Mandel replaced Hasselhoff in season five (2010). Howard Stern replaced Morgan in season seven (2012). Mel B replaced Osbourne in season eight (2013), while Heidi Klum joined as a fourth judge . Simon Cowell replaced Stern in season eleven (2016). Regis Philbin was the original host (season one), followed by Jerry Springer for two seasons (2007--2008), followed by Nick Cannon for eight seasons (2009--2016). Supermodel and host Tyra Banks replaced Cannon for the twelfth season (2017). </P> <P> On August 2, 2016, NBC renewed the series for a twelfth season, which premiered on May 30, 2017 . The season concluded on September 20, 2017 . </P> <Table> <Tr> <Th> Season </Th> <Th_colspan="2"> Duration </Th> <Th> Winner's prize </Th> <Th_colspan="3"> Finalists </Th> <Th> Presenter </Th> <Th_colspan="4"> Judges </Th> </Tr> <Tr> <Th> Premiere </Th> <Th> Finale </Th> <Th> Winner </Th> <Th> Runner - up </Th> <Th> Third place </Th> </Tr> <Tr> <Th> </Th> <Td> June 21, 2006 </Td> <Td> August 17, 2006 </Td> <Td> $1,000,000 </Td> <Td> Bianca Ryan </Td> <Td_colspan="2"> All That & The Millers </Td> <Td> Regis Philbin </Td> <Td> David Hasselhoff </Td> <Td> Piers Morgan </Td> <Td> Brandy Norwood </Td> <Td> N / A </Td> </Tr> <Tr> <Th> </Th> <Td> June 5, 2007 </Td> <Td> August 21, 2007 </Td> <Td> Terry Fator </Td> <Td> Cas Haley </Td> <Td> Butterscotch </Td> <Td> Jerry Springer </Td> <Td> Sharon Osbourne </Td> </Tr> <Tr> <Th> </Th> <Td> June 17, 2008 </Td> <Td> October 1, 2008 </Td> <Td> Neal E.
