There may never have been a fall television season as jam packed as the one we’re about to endure. New titans are arriving, dropping their generously financed catalogs into an already saturated market. The new wave of potential Netflix killers begins with the arrivals of the Apple TV Plus and Disney Plus streaming services on Nov. 1 and Nov. 12, each debuting with a small but buzzy roster of original series.

HBO and Netflix, meanwhile, are powering up in a season they’ve traditionally shied away from, trading prestige punches: HBO’s “Catherine the Great” with Helen Mirren versus Netflix’s third season of “The Crown” with Olivia Colman ; HBO’s state-of-the-world dramedy, “Mrs. Fletcher,” versus Netflix’s state-of-the-world dramedy, “The Politician.”

And then, this being an exhaustive new-show roundup, there are all the broadcast-network debuts, many of which won’t be spoken of here again. A couple picks to break out: “Stumptown” on ABC and “Almost Family” on Fox.
