Why NBC Pre-empted 'Revolution' for Boston Bombing Coverage Deadline

NBC was the only broadcast network to pre-empt its regular prime-time lineup to cover the deadly bombings at the Boston Marathon, and part of the reason had to do with the subject matter on "Revolution," reports.

An anchored news special with Brian Williams aired at 10 p.m. instead of the drama, which had been slated for the time slot. One issue that influenced the decision was that the plot of the "Revolution" episode was about efforts to find a nuclear bomb, which executives decided wasn't appropriate after the tragedy, the story adds.

"The pre-emption has serious repercussions for 'Revolution,' sending NBC’s scheduling team scrambling for solutions,” the story reports. “The problem is that, because of the drama’s late return to the schedule to coincide with the spring cycle of 'The Voice,' 'Revolution' was slated to air all 10 remaining new episodes with no interruption."

Without the pre-emption, the show would have ended past the finish of the season, with a finale airing May 27. But now "Revolution" may need to air its finale even later into the summer, a move that's frowned upon for top drama series, the story notes.

Another option is for NBC to air two originals in one week, keeping the May 27 finale date.
