This episode explores how “hello” became the standard telephone greeting. Originally used as an exclamation or call for attention, “hello” gained popularity when Thomas Edison recommended it as the ideal way to answer a phone. Alexander Graham Bell, in contrast, preferred “Ahoy!” But Edison’s suggestion caught on—first with operators, then the public—reshaping social norms. The episode also looks at global alternatives like “Pronto!” in Italy and “Moshi moshi” in Japan. Today, “hello” remains a universal expression of connection, born not from ancient custom, but from the technology of the modern age.
