These cartoons initially competed with the nationally broadcast ones. In the 1980s, national TV only aired Saturday mornings, not competing with the weekday and Sunday blocks of syndication aired by local independent stations but; however, by the 1990s, Fox and then WB started airing weekday afternoon blocks. By the end of the 1990s, both syndicated and national TV ended up losing most of its children's market to the rise of cable TV channels like Nickelodeon, Disney Channel and Cartoon Network which provided appealing children's entertainment throughout the week at nearly all hours.
