NBC announced Wednesday that instead of the the planned repeat of “America’s Got Talent,” it will take three consecutive nights to launch the first fall season of “The Voice.”

The network will add a third night of the singing competition series next Wednesday at 8.

That, of course, means that “The Voice’s” third night will air in the teeth of Fox’s return of its new-and-improved, or at-least-tarted-up-with-Brit-Brit-and-Demi, “X Factor.”

“The Voice’s” additional night of chair-swiveling blind auditions joins the previously scheduled season debut next Monday and Tuesday.

For brevity’s sake, NBC said Wednesday that it had “fashioned the fall season premiere of ‘The Voice’ into a three-night event.” In rough numbers, that means:

a.) The network would love to take a chunk of viewers away from the re-launch of “X Factor,” which reportedly coughed up $15 million for Britney Spears alone, not to mention Demi Lovato. That came after deciding that Paula Abdul and Nicole Scherzinger were among the reasons the show failed to open with the 20 million viewers that its creator and star, Simon Cowell, had promised. (The other reason apparently was show host Steve Jones, who is also gone.)

b.) After also coughing up $15 million to buy Howard Stern’s services, “America’s Got Talent” is averaging nearly 19 percent fewer viewers than last summer, and presumably an original episode of “The Voice” will provide a bigger lead-in audience for the season’s penultimate “AGT” episode than would have the scheduled repeat “AGT” episode.
