- In a 1998 Variety website article, Nickelodeon and United Paramount Network (UPN) were rumored to have began discussion for airing a two-hour block on the latter. Strong candidates for the block included KaBlam!, Rugrats, Hey Arnold! and The Secret World of Alex Mack. However, the block never came to be. Later that year, Disney worked with the network, airing on television during weekdays and Sunday mornings.
