Masterpiece will concentrate on bolstering its popular Classics and Mystery! strands with an boost in support from its main sponsor, Viking River Cruises.

The WGBH icon program’s footprint will expand by 50 percent — around 20 hours — with additional episodes spread throughout the season. Extra hours will be scheduled Sundays at 8 p.m. or 10 p.m. Eastern time, before or after Masterpiece’s longtime 9 p.m. time slot.
