in most markets, most affiliates use the network's current saturday morning schedule. some, such as atlanta's wupa-tv broadcast the block on sundays. this is usually done because the stations were at one time upn affiliates and upn did not have children's television programming on saturday mornings. former wb affiliate wcct-tv in hartford airs the first three hours of the block on saturday mornings and the last two hours on sunday mornings to make room for their own programing.
