Viewers on each end of the political spectrum, conservative Republicans and liberal Democrats, have favorite PBS shows, according to a yearlong study by the Experian Simmons consumer research firm. It wanted to see what programs indexed highest and lowest among those viewers. Masterpiece was the third-highest indexing show among liberal Democrats, behind only The Daily Show and Colbert Report, says the Washington Post, which noted, "Masterpiece indexes at a whopping 234, which means a Masterpiece viewer is 134 percent more likely to be a liberal Democrat than the average adult viewer."
Three shows on PBS also rank in the conservative Republican index: This Old House, New Yankee Workshop and Antiques Roadshow.
And Frontline is No. 10 among news shows for liberal Democrats.
Here are the complete lists from Experian Simmons.
