The 20-episode sixth season of History channel's flagship scripted series will end after its upcoming 20-episode sixth season. Vikings will finish airing its fifth season at the end of this month. But with Vikings ending, creator Michael Hirst, History and MGM Television are looking to extend the franchise with a new series, though no details have been revealed, according to Deadline. "Vikings has been a legacy show for History," Deadline's Nellie Andreeva points out. "It marked the network’s first foray into ongoing scripted series. Vikings was a breakout ratings hit when it debuted in 2013 and remains History’s #1 scripted series of all time, successfully overcoming a number of cast changes, including the exit of original lead, Travis Fimmel, whose character Ragnar Lothbrok’s story arc came to an end in Season 4. Vikings originally set out to follow the adventures of Ragnar Lothbrok (Fimmel) and tell the sagas of Ragnar’s band of Viking brothers and his family. Because it was based on actual historical figures and events, Vikings had a finite number of stories to tell, and had been building towards an end, set by Hirst as the creative mastermind behind the series."
