When Sherlock originally aired in the United States as part of PBS's Masterpiece, each episode was edited down to an hour, from the original 80-90 minute length. Will series 3 be similarly edited? Or will PBS air each full-length episode?
I watched the shows on the PBS broadcast. Each Masterpiece episode was allotted 2 hours - 90 minutes of that episode of Sherlock, followed by a 30 minute "Behind the scenes" type show about the episode that just aired.
So to your questions:
No, the episodes were not edited, and
Yes, PBS aired each full-length episode.
