Another question: About cable TV cartoons on network TV, how come the double-length episodes or seasonal episodes have been shown with the regular episodes in the Saturday morning block, rather than airing at night with the annual cartoon specials, ie a double-length Nickelodeon Christmas episode airing at 8 pm on CBS like Rudolph the Red-Nosed Reindeer and Frosty the Snowman? Are the double-length or seasonal episodes treated as regular episodes?
