CBS is banking on at least a few Big Brother fans not being terribly excited about NBC's coverage of the Winter Olympics. The network announced Friday that it's going to air the entire run of its upcoming "Celebrity" edition over just two weeks.

The new Big Brother will premiere Feb. 7, just two days before the Opening Ceremony in PyeongChang, and will air for a whopping 13 nights before wrapping Feb. 25. Its a rare move for CBS, which has aired Big Brother exclusively in the summer for years.

Big Brother won't be the only light reality show to go against the Olympics. ABC is also prepping a "Winter Games" edition of the Bachelor franchise.

Another CBS reality show, The Amazing Race, will also get a winter run — albeit over a longer period, kicking off Jan. 3. When it wraps up, Survivor will return to Wednesdays for its 36th cycle on Feb. 28.

CBS is saving its other big premieres for after NBC's Olympic window. Comedy Living Biblically moves into Monday nights at 9:30 p.m. on Feb. 26. Drama Instinct joins Sundays on March 11, airing in Wisdom of the Crowd's vacant 8 o'clock time slot.
