Protesters said the show's producers and writers helped normalise Trump's behaviour during the primaries.
"I feel like the media has already normalised his behaviour," SNL co-head writer Bryan Tucker said in an interview with Vulture a year after the episode aired. "Our job is not to promote one candidate or the other. Our job is to take what's already happening and make fun of it."
In the end, many tuned in to see just what would happen. Trump appeared on camera for 12 minutes in an episode that earned terrible reviews.
This season started off with Alec Baldwin debuting his biting Trump impersonation. About 8.3 million viewers tuned in, and the October 1 episode became SNL's highest-rated premiere since 2008.
The real-life presidential debate mocked during the premiere earned unprecedented ratings in its own right, drawing more than 84 million viewers.
SNL apparently understood a parody's potential for high ratings: The show rarely announces upcoming cameos, but it did just that when it released a trailer promoting Baldwin's Trump impersonation to complement Kate McKinnon's take on Hillary Clinton.
You think you're good at being a jerk on Twitter? You will now face the grandmaster of being a jerk on Twitter.
Aside from Trump parodies, these past few months of the late-night show have featured a series of notable sketches - some insightful political commentary, some downright silly - that inspired plenty of hot takes.
SNL has also managed to stay in the news cycle days after an episode airs -- thanks, in large part, to how Trump has responded to the show.
He's repeatedly tweeted his grievances, calling the show "unwatchable", "biased" and "not funny at all". Baldwin has tweeted back in kind, saying he will stop if Trump releases his tax returns.
"Did you see that my friend Mr Baldwin is in a Twitter feud with our president-elect?" SNL alum Tina Fey - who suggested to showrunner Lorne Michaels that Baldwin play Trump - said in an interview with David Letterman for the Hollywood Reporter.
Aside from making her sad that a Twitter feud is "so beneath a president," she said of Trump, "You think you're good at being a jerk on Twitter? You will now face the grandmaster of being a jerk on Twitter."
Earlier this month, Matt Lauer asked Trump three times why he wouldn't just stop watching the show.
Trump skirted the question, repeated his gripes and finally said, "Frankly, the way the show is going now, and you look at the kind of work they're doing, who knows how long that show is going to be on? It's a terrible show."
SNL returns in January with Felicity Jones as host.
