The Invisible Bedrock of the Modern World
There is a distinct sense of technological vertigo that comes with realizing your $1,500 smartphone—a device with more processing power than the entire world possessed in the mid-century—is essentially running on logic designed to play a "Space Travel" game on a dusty hallway computer in 1969. The C programming language is "invisibly everywhere." It is the digital scaffolding of the modern age: when you start your car, the mainboard uses C to orchestrate its components; when you check a notification on iOS or Android, you are interacting with a kernel written in C. As the industry saying goes, once you understand the lineage, you "can't unsee C." But if our entire digital civilization is anchored to the third letter of the alphabet, it begs a historical question: what happened to the rest of the letters?
Modern Computing Started with a High-Stakes Space Game
The story begins at Bell Labs—or simply "Bell Labs," as the locals will tell you, sans the definite article, much like one doesn't say "the Stanford." In the late 1960s, this institution was a government-backed monopoly owned by AT&T, a sprawling New Jersey playground with a massive budget and a hands-off approach to its resident geniuses.
In 1969, researcher Ken Thompson found himself with a bit of a problem. He wanted to play a game he’d written called Space Travel, but the lab’s primary project had been defunded. He was forced to retreat to an old DEC PDP-7 sitting in a hallway—a machine that was obsolete even by 1960s standards, boasting a meager 8 kilobytes of memory. To make the game run, Thompson had to build a new operating system from scratch, which we now know as Unix.
However, writing an OS in assembly code—a grueling nightmare of raw 1s and 0s—was a hacker's penance. Thompson needed a high-level language, but the existing standard, BCPL (Basic Combined Programming Language), was far too bulky for the PDP-7’s cramped hardware. In a move of classic "hacker spirit," Thompson performed a sort of software lobotomy on BCPL, stripping it down to its bare essentials to create a lean, fast language he called "B."
C Was Originally Just "New B"
B was a triumph of minimalism, but it was "typeless," which became a liability when Bell Labs upgraded to the more sophisticated PDP-11. The new hardware was expensive and powerful, capable of addressing different byte sizes efficiently, but B was wasting that potential by treating every piece of data as a generic "word."
This brought Dennis Ritchie, Thompson’s close collaborator, into the fray. Ritchie spent two years overhauling B to ensure Unix could thrive on the new hardware. His revolutionary innovation was the "Type System." By introducing specific types like char (for characters) and int (for integers), Ritchie allowed programmers to tell the machine exactly how much memory to allocate for a piece of data. It was the difference between using a sledgehammer and a scalpel. For a long while, the duo simply called the project "New B," but as it evolved into a distinct entity, they simply looked at the next letter in the alphabet and dubbed it C.
By 1973, they took the radical step of rewriting the core of Unix in C. At the time, this was heresy; everyone "knew" that only assembly code was fast enough for an operating system. As the historical record of the era notes:
"Before that, operating systems were always written in assembly code because everyone knew that high-level languages were too slow. C proved everyone wrong. It was fast, it was elegant, and most importantly, it was portable."
Why "D" Was Skipped for a Nerd Joke
By the late 1970s, C was the undisputed king of code. However, as software systems grew into sprawling monsters, Bjarne Stroustrup at Bell Labs realized C needed to evolve to support "Object-Oriented Programming"—a way to group data and logic into manageable "objects."
The logical progression suggested that the successor should be named "D." However, the culture of Bell Labs was steeped in linguistic puns. In the C language, if you want to increment a variable by one, you use the ++ operator (e.g., x++ means x + 1). Rick Mascitti, a colleague of Stroustrup, suggested the name "C++." It was a brilliant nerd joke: the name literally meant "C, but incremented."
This pun was so successful that it effectively hijacked the alphabetical timeline. The "D" slot remained a ghost in the machine for twenty years while C++ became the global standard for everything from the first web browsers to high-end video games.
The Real "D" Language is a High-Performance Niche Player
The actual D programming language didn't arrive until 2001, created by veteran compiler engineer Walter Bright. Bright was tired of the "clunky" nature of C++, which had become weighed down by the need to support legacy code from the 1970s. D was designed to offer the raw power of C with modern safety features that prevented the memory bugs responsible for the "blue screen of death."
D was technically superior in many ways, but it faced a classic market problem: timing. By 2001, the world was obsessed with Java and C#, and eventually, a language called Rust arrived to claim the "memory safety" crown. Today, D hasn't become king, but it remains a highly respected niche player used for high-performance tasks by:
- Netflix: For infrastructure and backend efficiency.
- eBay: For specialized high-speed data processing.
There Was an "A," But You Have to Dig for It
If C came from B, was there ever an "A"? While no language was officially dubbed "A" in this specific lineage, the grandparent of the entire family tree is ALGOL (Algorithmic Language, 1958). Unlike the lone-wolf creation of B or C, ALGOL was born from a committee of European and American scientists seeking a universal mathematical language.
ALGOL's DNA led to CPL (Combined Programming Language), which was too complex to be practical. CPL was then simplified into BCPL (the "Basic" version), which Ken Thompson used as the foundation for B. While B took its name from the first letter of its predecessor, the scientific bedrock of the entire alphabetical pyramid is the "A" of ALGOL.
The Bedrock of 2026
Decades after Ken Thompson just wanted to navigate a digital starship, we are still living in the house that C built. Even the "modern" languages of the 21st century, like Python and JavaScript, are usually interpreted by programs that are themselves written in C. It remains the bedrock of computing—a language born in a New Jersey laboratory to turn a giant calculator into a gateway for human ingenuity.
As we push toward an era of AI-generated code and quantum computing, it raises a compelling question: are we capable of building a future that isn't dependent on the shorthand of 1970s hackers, or is the foundation of our digital world already set in stone?
