The past has never been bigger on TV than it is today. From Norsemen invading England circa 800 in "Vikings" to Chinese immigrants heading to Orlando circa 1990 in "Fresh off the Boat," series set in the past are all the rage.
Some, like AMC's 1960s drama "Mad Men," are known for their scrupulous devotion to historical accuracy. Others, such as Starz's 18th-century pirate adventure "Black Sails," take a more liberal interpretation. But in all cases the series revel in their settings.
