In the TV business, seasons are the time period where new and returning shows debut, usually running from September to May each year. NBC, CBS, ABC, Fox, and The CW all put their best stuff on in the Fall, and debut a few extra shows later on mid-season. That's how they always operated, and that's how they will continue to operate till the end of time. By contrast however, Cable and Streaming networks have always just debuted seasons and shows whenever they felt like it. They don't stock pile most of their premieres for the Fall, instead spreading them out over the course of the September - May period, some even premiering in the summer. So why aren't these types of networks beholden to the traditional TV season rules?
