That actually wouldn't be a bad idea. Perhaps like Part 1 could be the origins of SST, leading up to its first season; Part 2 could be the show finding its footing and reaching out to disadvantaged children throughout the 70s; Part 3 could be the show's rising success throughout the 80s; Part 4 could be all of the shake-ups and the different turns it started to take in the 90s; Part 5 could be how it continues to try to maintain its relevance in a world filled with alternative educational shows up till today.
