When Adobe introduced Type 1 in 1984, it changed what a letter was made of. Instead of storing each glyph as a fixed grid of dots, Type 1 described every character as a cubic Bézier curve: a smooth path traced from a handful of control points. Because the shape was mathematical rather than pixel-bound, a single file could scale to any size and stay crisp, whether set for a footnote or a billboard.

This was the quiet engine beneath desktop publishing, the reason ordinary people could suddenly typeset pages that looked professionally printed. But the format was encrypted and proprietary, and Adobe licensed it for real money. Having lit the fuse on the desktop-publishing revolution, the company effectively taxed it, collecting on the very tools it had made possible. For years that was simply the price of entry. The story carries a final irony worth pausing on. In January 2023 Adobe retired support for Type 1 in its own software.

The format that opened the door no longer opens at all inside the applications that were built around it. Files that once set the standard now sit inert, readable only through conversion, a reminder that even foundational technology can be quietly withdrawn. Type 1 is where outline type begins, and studying it is a way of understanding everything that followed: the curves, the scalability, the business models, and the long argument over who owns the alphabet on your screen.
