In December, Stephen Colbert told CBS’s John Dickerson in an interview, “Now I have no choice but to actually enjoy this incredible gift every day that Mr. Trump will be,” referring to the oft-repeated notion that President Trump would be a boon to late-night comedy shows.

On Thursday, researchers at George Mason University released a study that aimed to quantify exactly how much of a gift Mr. Trump has been. According to the study, Mr. Trump was the subject of 1,060 jokes from the leading late-night talk-show hosts in his first 100 days in office — far surpassing the number of jokes other recent presidents attracted in their entire first year in office. There were 936 directed at Barack Obama in 2009, and 546 toward George W. Bush in 2001. Bill Clinton had only 440 jokes in 1993.

The study counted “The Late Show With Stephen Colbert,” “The Tonight Show Starring Jimmy Fallon,” “Jimmy Kimmel Live!” and “The Daily Show With Trevor Noah.” It notably did not include “Full Frontal With Samantha Bee.”

The study also said that Mr. Colbert made the most jokes at the expense of Mr. Trump (337), followed by Mr. Noah (315), Mr. Fallon (231) and Mr. Kimmel (177).
