PBS has scheduled the eight-week run of the hit English period drama to run through the end of February, Masterpiece executive producer Rebecca Eaton said today during the PBS Annual Meeting. Downton Abbey is the highest-rated drama in PBS history after its third-season finale drew 8.2 million viewers on February 17, a 50% increase from the Season 2 ender. The timeframe for the PBS airdates falls similar to last year, coming after the fall run of the series on ITV in the UK. The big ratings bumps in the U.S. were notable given the high-stakes spoilers that were parading around the Internet while the show was airing across the pond ahead of its U.S. broadcast. ITV doesn’t announce its schedule until a couple of weeks before shows debut, but a September run there is likely again for the Carnival/Masterpiece co-production.
