OPINION: Colbert and the End of Late-Night TV

Mr. Colbert deserves criticism for pursuing a niche segment through politicization, but the digital explosion inevitably means smaller average audiences—and less shared experience—for each particular program. That’s why the news here isn’t Mr. Colbert’s firing but rather the mothballing of the Late Show itself. The myth of monoculture is retiring.

Political content with a splash of comedy isn’t exiting the stage; it retains a narrow but deep audience. That’s why “Gutfeld!,” the Fox evening show that also doesn’t attempt to persuade or entertain beyond its core audience, has a significantly larger viewership than the Late Show. But it does so on cable, not pretending to be a part of a broadcast common culture.

That, ultimately, is why the end of the Late Show matters historically. Mr. Colbert wasn’t attempting something as important as what Carson did—or his heirs David Letterman, Jay Leno and Conan O’Brien. As much as they made a meaningful mark on American culture, they weren’t essential to the life of the republic. But this fading of an era is occasion to acknowledge that having some shared things does matter to a stable political culture.

The Founders fully understood. When Publius wrote about the preconditions for a free society in Federalist 2, he declared Americans “one united people . . . speaking the same language, professing the same religion, attached to the same principles of government.” The Constitution requires a certain amount of unity, at least a minimal shared conception of the common good. The monoculture of the 20th century was by no means robust enough for what the Founders thought we must share, but as it fades to black and we’re increasingly siloed by algorithms and the digitization of daily life, it’s important to understand together that we’ll likely never again have a shared mass culture to unite us.

America depends on a shared sense of “we.” Boomers and Gen X once found some of that on late-night TV. For millennials and Gen Z, a fragmented media ecosystem that’s insufficiently popular to sustain a common culture presents real challenges. Any revolution would not be televised—it would be streamed from a thousand angles across a million platforms. 

The task of rebuilding a shared Constitutional civics thus has never been more urgent.
