the NFL, Fox firmly established itself as the nation's fourth major network. Fox Television Stations would acquire New World outright on July 17, 1996, in a $2.48 billion stock purchase, making the latter's twelve Fox affiliates owned-and-operated stations of the network; the deal was completed on January 22, 1997. Later, in August 2000, Fox bought several stations owned by Chris-Craft Industries and its subsidiaries BHC Communications and United Television for $5.5 billion (most of these stations were UPN affiliates, although its Minneapolis station KMSP-TV would rejoin Fox in September 2002 as an owned-and-operated station). These purchases, for a time, made Fox Television Stations the largest owner of television stations in the U.S. (a title that has since been assumed by the Sinclair Broadcast Group, one of the network's largest affiliate groups). Evolving programming Fox completed its prime time expansion to all seven nights on January 19, 1993, with the launch of two additional nights of programming on Tuesdays and Wednesdays (The method of gradually adding nights to the programming schedule that began with the network's April 1987 prime time launch was replicated by The WB and UPN when those networks debuted in January 1995), making it the fifth broadcast network (behind the Dumont network) to air programming on a nightly basis. September 1993 saw the heavy promotion and debut of a short-lived western series that incorporated science-fiction elements, The Adventures of Brisco County, Jr. However, it was the supernatural investigative drama that debuted immediately following it on Friday nights, The X-Files, that would find long-lasting success, and would become Fox's first series to crack Nielsen's year-end Top 20 most-watched network programs. After several other failed attempts at late night programming following the cancellation of The Late Show (most notably, the quick failure of The Chevy Chase Show in 1993), Fox finally found success in that time period with the debut of MADtv on October 14, 1995; the sketch comedy series became a solid competitor to NBC's Saturday Night Live for over a decade and was the network's most successful late night program as well as one of its most successful Saturday night shows, running for 14 seasons until 2009. An attempt to make a larger effort to program Saturday nights by moving Married... with Children from its longtime Sunday slot and adding a new but short-lived sitcom (Love and Marriage) to the night at the beginning of the 1996–97 season
