The gift is the largest yet for the Masterpiece Trust, a fund-raising initiative started last year, PBS said Wednesday. The donor is Darlene Shiley of San Diego, who previously gave $250,000 to support "Masterpiece."
The drama showcase scored a hit with the second season of "Downton Abbey," which drew a total of 17 million viewers to make it the most-watched "Masterpiece" miniseries on record, PBS said.
"Masterpiece," from WGBH Boston, began searching for new funding sources after losing longtime sponsor Exxon Mobil in 2004. The series finally gained a new corporate supporter last year when Viking River Cruises came aboard.
