C
Designed by Dennis Ritchie in 1972 at Bell Labs, it gave birth to Unix and drove the rewrite of that operating system into a portable form. Over 90% of the world's operating system kernels—including Linux, Windows, and macOS—are built directly in C or its close derivatives, making it the bedrock of modern computing. This language defined the paradigms of memory management, pointer arithmetic, and low-level hardware control that subsequent languages have either adopted or deliberately avoided. Because of its efficiency and direct hardware access, C outperforms the average modern language in execution speed and memory footprint, powering everything from embedded microcontrollers to supercomputers. Without C's rigorous foundations, the entire software ecosystem—including Python's CPython interpreter and Java's JVM—would not exist as we know them.

Frequently Asked Questions

### Which programming language has had the most influence in history? C is widely regarded as the single most influential language ever created. Nearly every modern operating system — Windows, Linux, and macOS — is built on C at its core, and its syntax directly shaped C++, Java, Python, and scores of others still in active use today.

### Why do decades-old languages like COBOL and FORTRAN still matter? Influence is not the same as popularity. COBOL alone is estimated to process 95 % of ATM transactions worldwide every day, while FORTRAN still powers the climate-simulation and aerospace models that modern science depends on. Longevity of real-world deployment is the truest measure of a language's impact.

### Which language on this list should a complete beginner learn first? Python. Its English-like, readable syntax lowers the barrier to entry dramatically, and its dominance in data science, machine learning, and automation means beginners gain immediately marketable skills from day one.

Frequently Asked Questions About Influential Programming Languages

What makes a programming language influential? A language earns influence by shaping the design of later languages, enabling entirely new computing domains (scientific computing, the web, AI), or achieving adoption at massive scale — often all three. The [TIOBE Index](https://www.tiobe.com/tiobe-index/) and the annual [Stack Overflow Developer Survey](https://survey.stackoverflow.co/) are two widely cited benchmarks for measuring real-world language reach.

Which programming language should a beginner learn first in 2026? Python consistently tops beginner recommendations because its readable syntax mirrors plain English, its ecosystem spans data science, web development, and automation, and it ranks #2 on this list of the most influential programming languages ever created.

Is COBOL still used today? Yes. Despite its 1959 origins, COBOL powers an estimated 95% of ATM transactions and processes over $3 trillion in daily commerce, primarily across banking and government mainframe systems — making COBOL developers surprisingly in demand even now.
