Repercussions of the 1994–1996 United States broadcast TV realignment

Between 1994 and 1996, a wide-ranging series of network affiliation switches took place in media markets across the United States as the result of a multimillion-dollar deal between Fox and New World Communications which was announced on May 23, 1994. The Fox–New World agreement, which saw twelve stations owned by New World change affiliations to Fox, initiated some of the most sweeping changes in American broadcasting history. This deal, and the ancillary deals that followed, created a domino effect and presented a wide-ranging series of ramifications that have impacted local broadcasting up to the present day.

Rise of Fox in prime time
Prior to the affiliation switches, Fox largely catered to the 18–34 demographic with younger-skewing shows and an "irreverent, sometimes sophomoric" style typified by Married... with Children and The Simpsons, the latter the network's first definitive hit. Emphasis was given to Black audiences with shows like The Sinbad Show, Martin, Living Single and New York Undercover. Sketch comedy series In Living Color gained national attention for broadcasting a live episode against the Super Bowl XXVI halftime show that was a ratings success. The debut season of teen-oriented Beverly Hills, 90210 had a controversial storyline centering around the loss of a character's virginity, unprecedented in network television. Fox expanded their prime time schedule incrementally, resulting in the network programming seven nights a week by the 1993–94 season. Entering that season, Fox heavily promoted The Adventures of Brisco County, Jr. intending for it to be their next hit show, but it was the show following it on Friday night, The X-Files, that became a sleeper hit instead. Fox's reputation by 1993 was still largely limited to hits like The Simpsons along with a string of failed shows that attained similar levels of notoriety. The network attempted to re-enter late night with The Chevy Chase Show but was cancelled after six weeks amid negative reviews and dismal ratings.

Fox Kids, which had been created as a joint venture between Fox and the affiliates in 1990, continued after the realignment with a roster of affiliates considerably different from the main Fox network. WBNX-TV and KSMO-TV saw their profiles boosted with the addition of Fox Kids: KSMO experienced dramatic viewership increases in the early afternoon, while WBNX became Cleveland's WB affiliate in 1997 owing to their success with Fox Kids. Facing increased competition from basic cable channels along with Kids' WB and UPN Kids, Fox Kids merged their in-house production arm with Saban Entertainment (who produced Mighty Morphin Power Rangers for the program block) to form Fox Kids Worldwide in 1996, purchased The Family Channel the following year and relaunched it as Fox Family Channel. By 1998, Fox Kids affiliates sold their ownership interests back to Fox in a deal where Fox affiliates would pay a combined $50 million per year for Fox's renewed NFC contract. Fox Family Channel struggled to find viewership and lost money, and Fox–Saban sold Fox Kids Worldwide to The Walt Disney Company in 2001. Fox Kids' operations were reassigned to the network proper and were ultimately replaced with a program block from 4Kids Entertainment in 2002.

90210 and spin-off Melrose Place became hit shows, with Fox ordering 32 and 35 episodes for each show in the 1995–96 television season; The Simpsons alone had 25 episodes commission for their sixth and seventh seasons.

Fox's entertainment programs have also benefited from the heavy promotion they received during the sports telecasts, including shows that it already aired at the time, as well as newer programs (such as American Idol, 24 and House). In fact, Idol was the highest-rated prime time network program for eight consecutive seasons, from 2003–04 to 2010–11, the longest such streak in U.S. television history.
