That year, 2014, was when Obamacare health insurance plans began taking effect.
On Facebook, Axios noted, a clip of the monologue got more than 14 million views and 230,000 reactions in less than 24 hours. Kimmel's Facebook posts normally don't receive more than 1 million views, according to Axios.
And on Instagram, Kimmel's monologue about doubled the average engagement for his posts, receiving almost 123,000 views and more than 20,000 likes.
But the most dramatic disparity was on Twitter, where the emotional video got more than 31,000 retweets as of Wednesday.
"His tweets typically don't earn more than a couple of hundred retweets," Axios noted.
Axios' Mike Allen wrote that a veteran of the Obama White House told him that Kimmel "killed the Republicans' already shaky efforts to revive the House's health-care reform."
That may be overstating the effect of Kimmel's monologue somewhat, since the GOP Obamacare replacement bill was already in trouble, and has been more nearly two months since Republican leaders scrapped a planned vote on it.
But his story and comments underscored the concerns that a number of House Republicans are struggling with as their leaders try to get them to vote for a new version of the legislation, known as the American Health Care Act.
That bill was dealt two serious blows on Monday and Tuesday when GOP Reps. Billy Long and Fred Upton said they would vote no on the bill because of worries that it would negatively affect people with pre-existing conditions.
The defections ended Republican hopes that a vote on the bill could take place on Wednesday. GOP leaders say they won't call that vote until they have the votes to pass it, and as of now there are almost enough "no" votes from Republicans, coupled with undecided GOPs members, to ensure that the bill would fail.
Trump met Wednesday with Upton and Long to discuss their concerns.
Politico reported later that both congressmen now will support the bill after the addition of an amendment to alleviate their concerns. That amendment would add $8 billion in federal funding to constrain insurance costs for people with pre-existing conditions who face higher premiums as a result of letting their insurance plans lapse.
