You may have noticed that every popular movie these days is a remake, reboot, sequel, spinoff, or cinematic universe expansion. In 2021, only one of the ten top-grossing films––the Ryan Reynolds vehicle *Free Guy––*was an original. There were only two originals in 2020’s top 10, and none at all in 2019.

People blame this trend on greedy movie studios or dumb moviegoers or competition from Netflix or humanity running out of ideas. Some say it’s a sign of the end of movies. Others claim there’s nothing new about this at all.

Some of these explanations are flat-out wrong; others may contain a nugget of truth. But all of them are incomplete, because this isn’t just happening in movies. In every corner of pop culture––movies, TV, music, books, and video games––a smaller and smaller cartel of superstars is claiming a larger and larger share of the market. What used to be winners-take-some has grown into winners-take-most and is now verging on winners-take-all. The (very silly) word for this oligopoly, like a monopoly but with a few players instead of just one.

I’m inherently skeptical of big claims about historical shifts. I recently published a paper showing that people overestimate how much public opinion has changed over the past 50 years, so naturally I’m on the lookout for similar biases here. But this shift is not an illusion. It’s big, it’s been going on for decades, and it’s happening everywhere you look. So let’s get to the bottom of it.

(Data and code available here.)

Movies

At the top of the box office charts, original films have gone extinct.

I looked at the 20 top-grossing movies going all the way back to 1977 (source), and I coded whether each was part of what film scholars call a “multiplicity”—sequels, prequels, franchises, spin-offs, cinematic universe expansions, etc. This required some judgment calls. Lots of movies are based on books and TV shows, but I only counted them as multiplicities if they were related to a previous movie. So 1990’s Teenage Mutant Ninja Turtles doesn’t get coded as a multiplicity, but 1991’s Teenage Mutant Ninja Turtles II: The Secret of the Ooze does, and so does the 2014 Teenage Mutant Ninja Turtles remake. I also probably missed a few multiplicities, especially in earlier decades, since sometimes it’s not obvious that a movie has some connection to an earlier movie.

Regardless, the shift is gigantic. Until the year 2000, about 25% of top-grossing movies were prequels, sequels, spinoffs, remakes, reboots, or cinematic universe expansions. Since 2010, it’s been over 50% ever year. In recent years, it’s been close to 100%.

Original movies just aren’t popular anymore, if they even get made in the first place.

Top movies have also recently started taking a larger chunk of the market. I extracted the revenue of the top 20 movies and divided it by the total revenue of the top 200 movies, going all the way back to 1986 (source). The top 20 movies captured about 40% of all revenue until 2015, when they started gobbling up even more.

Television

Thanks to cable and streaming, there's way more stuff on TV today than there was 50 years ago. So it would make sense if a few shows ruled the early decades of TV, and now new shows constantly displace each other at the top of the viewership charts.

Instead, the opposite has happened. I pulled the top 30 most-viewed TV shows from 1950 to 2019 (source) and found that fewer and fewer franchises rule a larger and larger share of the airwaves. In fact, since 2000, about a third of the top 30 most-viewed shows are either spinoffs of other shows in the top 30 (e.g., CSI and CSI: Miami) or multiple broadcasts of the same show (e.g., American Idol on Monday and American Idol on Wednesday).

Two caveats to this data. First, I’m probably slightly undercounting multiplicities from earlier decades, where the connections between shows might be harder for a modern viewer like me to understand––maybe one guy hosted multiple different shows, for example. And second, the Nielsen ratings I’m using only recently started accurately measuring viewership on streaming platforms. But even in 2019, only 14% of viewing time was spent on streaming, so this data isn’t missing much.
