had failed because it programmed just under the number of hours defined by the FCC to legally be considered a network. This allowed Fox to make revenue in ways forbidden to the established networks (for instance, it did not have to adhere to the Financial Interest and Syndication Rules that were in effect at the time), since during its first years it was considered to be merely a large group of stations. By comparison, DuMont had been saddled by numerous regulatory barriers that hampered its potential to grow, most notably a ban on acquiring additional stations, during an era when the FCC had much tighter ownership limits for television stations (limiting broadcasters to a maximum of five stations nationwide) than it did when Fox launched. In addition, Murdoch was more than willing to open his wallet to get and keep programming and talent. DuMont, in contrast, operated on a shoestring budget and was unable to keep the programs and stars it had. Most of the other startup networks that launched in later years (such as The WB, UPN and The CW) followed Fox's model as well. Furthermore, DuMont operated during a time when the FCC did not require television manufacturers to include UHF capability. In order to see DuMont's UHF stations, most people had to buy an expensive converter. Even then, the signal quality was marginal at best compared to the signals of VHF stations . By the time Fox launched, cable allowed UHF stations to generally be on an equal footing with VHF stations. Although Fox was growing rapidly as a network and had established itself as a presence, it was still not considered a major competitor to the established "Big Three" broadcast networks, ABC, CBS, and NBC. From its launch, Fox had the advantage of offering programs intended to appeal toward a younger demographic adults between 18 and 34 years of age – and that were edgier in content, whereas some programs that were carried by the "Big Three" networks attracted an older-skewing audience. Until the early 1990s, when Fox expanded its programming to additional nights and outside prime time, most Fox stations were still essentially formatted as independent stations – filling their schedules with mainly first-run and acquired programming, and, during prime time, running either syndicated programs or, more commonly, movies on nights when the network did not provide programming. Few Fox stations carried local newscasts during
