Fall no longer belongs to the networks. The season, once known as the exclusive launching spot for new NBC, ABC, Fox, CW, and CBS comedies and dramas, is now also used liberally by HBO, Showtime, Netflix, Amazon, and every other TV outlet trying to peddle original series. In the next two months, some three dozen newbies are going to drop, and one-third of them will come from non-network sources.

In other words, keep your digital umbrellas at hand for the deluge, which, of course, includes returning series. It’s the peak period for an era known as Peak TV. From CBS’s “Bull’’ and ABC’s “Speechless’’ to HBO’s “Divorce’’ and Amazon’s “Crisis in Six Scenes,’’ the wannabe TV obsessions will be raining down. You will be overwhelmed with options, and your DVR queues will groan.

The down side: A few good things will probably slip through the cracks and get undeservedly canceled. The up side: You will nevertheless find the kind of variety that never seemed possible in the old days. Yes, there are plenty of procedurals (“Pure Genius’’), remakes (“Lethal Weapon’’), and idiotic, regressive sitcoms (“Kevin Can Wait’’), almost all of which are on the networks. But the season will also usher in a number of more inventive new efforts — “Designated Survivor,’’ ABC’s terrific new Kiefer Sutherland vehicle, for example, and NBC’s heartfelt ensemble drama “This Is Us.’’

Among the more unusual newcomers, HBO’s “Westworld’’ is bound to fascinate, as it dives deep into the relationship between human beings and artificial intelligence. I’m not sure TV has ever featured a series like HBO’s “Insecure,’’ Issa Rae’s low-key and insight-filled exploration of race and self-identity. Amazon’s “Good Girls Revolt’’ picks up on the themes of “Mad Men,’’ as it takes on women and equality in the workplace in 1970.

Time to get new batteries for your remote.
