If you've spent much time on the internet, you've seen a meme like the ones above: a picture, white words, a black outline, and the same exact font.

It's described everything from cats:

To German chancellors:

Why do so many memes have the same appearance?

The answer tells us something about design, business, and how technology can help something stupid find traction.

The meme font was unleashed in 1965, with a typeface called Impact

That meme typeface is called Impact (technically, a "font" is a specific version of a typeface, like when it's italicized or in bold). Though Impact feels like the quintessential internet typeface, it was released in 1965.

In 2004, Geoff Lee told the now-defunct Typophile forum how he designed the typeface back in the day, using hand-cut metal to create each letter. A couple of years after creating Impact, Lee sold the typeface to the type foundry Stephenson Blake.

Stephenson Blake's early marketing materials show that from the beginning, Impact was valued for its legibility, especially over pictures. It was easy to read its thick letters even without a black outline. This picture from the original brochure looks like a modern meme:

So from the beginning, Impact's thick letters were designed to stand out (similar to its close cousin Haettenschweiler, which is a little narrower).

But it took more than great design for Impact to become the default meme font.

How Impact came to rule the digital age

When Geoff Lee created Impact in the '60s, he couldn't have anticipated that his typeface would become a digital titan. But there's a reason Impact rose above other typefaces with wide, easy-to-read letters: It had distribution.

As the digital age began, Impact got key placement thanks, in part, to the dissolution of the firm that commissioned the typeface. Impact was Stephenson Blake's second-to-last typeface. As the firm slowly shifted its focus away from type, it divvied up digital rights among former competitors. Impact ended up in the hands of Monotype. Monotype, in turn, licensed key fonts to Microsoft.

The lead for Impact built off a key decision in 1996, when Impact became one of the "core fonts for the web" — a Microsoft-curated attempt at a standard font pack that would work across the internet. Impact built off that lead when it was included in the market-dominating Windows 98 operating system, while some close competitors weren't. Though Arial Black and the much-maligned Comic Sans provided some competition, neither was quite as legible over images.

Existing on millions of computers and standardized across the web, Impact was primed to become the de facto font of the meme. People created early memes using MS Paint or Photoshop, but websites that generated image macros (a fancy name for text on picture memes) also became part of the scene. In 2003, Impact had a threshold moment when someone made the most memorable cat meme ever (note that it lacks the distinctive black outline common today, yet is still legible, thanks to Impact).

As more and more memes used Impact, the momentum was hard to reverse.

Will Impact stick around as the meme font of choice?

There have been attempts to innovate on meme form — apps like Super put text in boxes to improve legibility, and even sites like Vox experiment with adjusting darkness on background photos to use more respectable fonts.

But by this point, the meme font has itself become a meme — a viral idea that's very difficult to suppress. We expect memes to look a certain way, and that way includes Impact. The font is as legible as ever, and it resists user error, too (if somebody forgets the outline, adds a weird shadow, or even screws up the color, it will still look like a "proper" meme).

And Impact's advantages are likely to endure. That old 1965 brochure actually articulated them pretty well, in surprisingly meme-like language. You can imagine a cat saying Stephenson Blake's pitch for Impact, both in 1965 and for years to come:

"Quite different and so good," indeed.

Updated: A reader notes that a metal typeset font, like the ones Lee cut, is not just the style, like Helvetica Bold, but also includes the size, like Helvetica Bold 11pt (this article originally only noted the style distinction).
