 Following the severe changes in the television landscape, such as the rise of the Fox network and cable television, the Financial Interest and Syndication Rules were abolished completely in 1993.It was the repeal of fin-syn that ultimately made newer broadcast networks such as UPN and The WB financially interesting for their highly vertically integrated parent media conglomerates Paramount Pictures (Viacom) and Time Warner, respectively.On average, the number of shows that have been broadcast during prime time by the three main networks (CBS, NBC and ABC) per season has ranged between 63 and 75 shows between the 1987-88 and 2001-02 seasons.
