network also began to broadcast the second half of the Thursday Night Football season in a simulcast with NFL Network in November, effectively breaking those shows' seasons into half-seasons. In May 2017, NBC announced the return of the Must See TV branding, with Will & Grace and Great News set to air on Thursdays for the 2017–18 season in addition to Superstore and The Good Place. Outside of holiday specials for Will & Grace and Superstore, again all four shows had their seasons broken up by Thursday Night Football. With Fox merging the package into theirs in the 2018 season, this will not occur for NBC again for the next five seasons, and only the traditional Thanksgiving and Christmas hiatuses will happen in future seasons.

Because of the 2007–2008 Writers Guild of America strike, shows that would regularly air were replaced with reruns and unscripted programming. A few episodes of Deal or No Deal occupied the 8:00 p.m. time slot on Thursdays during the strike. During the second half of the 2014–15 season, The Slap initially occupied the 8:00 p.m. time slot; it was moved to the 10:00 p.m. time slot midway through its run after Allegiance was canceled.
