Here I am talking about first-run episodes, or when a new episode debuted on and on what channel. I am NOT talking about what channel reruns aired on. I might mention it here and there with MMPR S1 for example. I also might mention what channels carried the season the year it aired. If it wasn't the year it first aired, I don't mention the channel is basically what I am saying. Also, I am ONLY covering the United States, not what channels the show has aired Internationally because I am talking about first-run ever in the whole world. And the U.S. got the 'world' premiere except for of course SPD's "Wormhole" that aired in Canada and "Mystic Fate" two-parter in the UK. Through the 17 seasons, Power Rangers has aired on a lot of channels and on different days. And the network executives have really toyed with kids when the show would even air! Sometimes an episode would air on Saturday one month and then Wednesday on another or even on a Sunday on a completely different channel for one week!
I had to do a lot of research from the PRC Episode Guide, TV.com and using a calendar and my own recollection.
