Soap operas in the age of pre-internet appointment television dealt with this problem in an interesting way. If you missed an episode or missed the entire week, you could always buy the latest issue of Soap Opera Digest which would have a summary of the week (or month's) story arc. Once a year or so, there would be magazines which would summarize the entire story arc of the show so new viewers could catch up. On a side note, if anyone is bored at work today, look up the Wikipedia entry for a long-running soap, like Days of Our Lives, which will have a synopsis of the entire story. It's quite epic, silly, and tawdry with a decades-long, no-breaks, no-jumps storyline.

I think for prime time viewing, Hill Street Blues was the first semi-serialized drama intended for viewers outside of the soap market. It had an interesting structure with A, B, and C plots. A plot gets resolved in a single episode. B plot is a 3-4 episode arc. And C plot lasts for the season. And then there was continuity from season to season. The show was decently successful, and paved the way for what we have now. One thing I find interesting is how many older viewers at the time thought it was too fast paced, too complex, and didn't enjoy it. They were too conditioned to the episodic norms. I'm sure the show would seem slow now to modern binge watchers.
