“The Real King’s Speech” (6 p.m., Discovery) examines the real-life drama behind the Oscar-winning motion picture. The story of George VI and his stammer has only recently come to light.

“Real” examines the pressures brought to bear on an extraordinarily shy man who had had never expected to ascend the throne. Thrust into the role after the abdication of his brother, George was the first monarch of the emerging radio age. World leaders from Franklin Roosevelt to Adolf Hitler had made much of the mass media, so in order to lead, George VI knew that his voice would have to enter the intimacy of every parlor in Great Britain.

• The network that brought us “Dirty Jobs” now delivers “Filthy Cities” (7 p.m., Discovery). Host Don Wildman uses computer graphics to “travel” back in time to visit urban areas at their most squalid.

First up is Medieval London, a 14th-century dungheap where 80,000 people were packed into one square mile. Next Wildman visits “New Stinking York” (8 p.m.) a technical rendering of Manhattan in the 19th century, a place teeming with immigrants who arrived only to discover that the streets weren’t exactly paved with gold.

• The Hallmark Channel never sets their movies in Filthy Cities. Tonight’s offering “The Shunning” (8 p.m., Hallmark) takes place in Lancaster, Pennsylvania’s “Plain” community where a soon-to-be married Amish girl discovers that she was not born to the faith, but given up for adoption as an infant. This throws a wrinkle into her wedding plans and leaves the would-be bride caught between two worlds. Sherry Stringfield stars.
