 UPN Kids launched on September 10, 1995 with a one-hour (the block expanded to two hours per week in 1996) block of cartoons (such as "Space Strikers" and "Teknoman"); unlike NBC, ABC, CBS, Fox and The WB (the latter of which debuted its own children's program block, Kids' WB, the day before UPN Kids made its debut), UPN ran its weekend morning children's programs on Sundays instead of Saturdays.This was likely due to several UPN affiliates in large markets also dually carrying the Fox Kids block for newer Fox stations (especially those of New World Communications; the former Fox affiliates in those markets mainly also retained the Fox Kids schedule) on Saturday mornings, who refused to carry Fox Kids in order to instead expand Saturday morning newscasts or retain other local programming.This eventually proved to be a conflict for UPN, as the more well-known Fox Kids block was given primacy in advertising and promotions by those affiliates (including the continuation of the local children's Fox Kids fan clubs run by those stations) over UPN's unproven children's programming.
