The iconic programming phrase "Hello, World!" was popularized globally by computer scientist Brian Kernighan, who first utilized the simple test phrase in his internal 1978 Bell Laboratories memorandum titled A Tutorial in the B Programming Language. He subsequently cemented its legendary status across computer science education by featuring the program in the seminal 1978 textbook The C Programming Language, co-authored with Dennis Ritchie, making it the universal introductory exercise for student programmers learning a new language.
