announced that it would merge the operations of the network and 20th Century Fox Television into the newly created Fox Television Group, with 20th Century Fox Television co-chairpersons Dana Walden and Gary Newman appointed to head the division. The 2014–15 season saw the series finale of Glee and debut of hits in the freshmen dramas Gotham (based on the Batman mythos) and the Lee Daniels-produced Empire. Ratings for Empire, in particular, increased week-to-week throughout its first season, becoming the network's first successful American Idol lead-out since House, as well as the first American television program to consistently increase its episode-to-episode viewership during its first five weeks since the 1992 feat set by ABC's Roseanne.

By 2016, Empire and The X-Files ranked in the Nielsen Top 10 for the season, the first season with 2 Fox programs entering the top rankings since the American Idol-House tandem of the 2007–2008 season (and the first ever season that Fox achieved such rankings without American Idol or any other reality television show from Fox in the Top 10). The same year also marked the finale of American Idol in its original run on Fox after airing for fifteen seasons, ending an era of one of the most successful shows in U.S. television history. In February 2017, Fox broadcast Super Bowl LI, which attracted an
