As planned, Persons Unknown has the night off tonight when NBC will air the Visa Gymnastics Championship. Also as planned, it returns next week. But, in a new wrinkle with a weird scheduling twist, it's ending a week early on August 28th instead of September 4 (the Saturday before Labor Day).
Originally the schedule called for the 10th episode on August 21, both the 11th and 12th episodes on August 28 and the finale on September 4th. NBC will air a repeat of Law & Order: Criminal Intent on September 4th at 8pm instead.
The strange thing is that according to The Futon Critic the 11th episode will never air at all, and will only be available online before the two hour finale (12th and 13th episodes) airs on August 28.
Why not just pull the last four episodes and put them online? Last week, it barely managed a 0.4 rating with adults 18-49 and 1.26 million viewers. It has consistently been NBC's lowest-rated hour of primetime.
