Schoolhouse Rock first showed up in the U.S. in the 1970s as an interstitial cartoon that aired during Saturday morning cartoons, like a commercial right before the 10:00am cartoon shows. Below is a table of when each season began. The total list of episodes is exactly 64, which fits our brackets precisely!
| Theme | Episodes | First Aired |
| Multiplication Rock | 11 | January 6, 1973 |
| Grammar Rock | 9 | September 15, 1973 |
| America Rock | 12 | September 20, 1975 |
| Science Rock | 9 | September 16, 1978 |
| Computer Rock | 4 | 1982 |
| Money Rock | 8 | May 7, 1994 |
| Earth Rock | 11 | March 31, 2009 |
There was no good way to divide them up by category or topic into groups of 16, so I separated them evenly into the four divisions. Example: There are 12 America Rock episodes, so I put three in each division. After dividing them into four groups, I arranged them in the brackets to balance the popular ones and spread them out. Much like actual ranking but without the numbers.
