Before the advent of modern recording and broadcasting technologies, fame and recognition were typically limited to a local or regional level. Singers gained popularity through their performances in theatres, concert halls, or other public venues, but their reach was limited by geographical boundaries.
It wasn't until the early 1900s, with the invention of the phonograph and later the radio, that the concept of a globally recognised singer emerged. One of the earliest examples of an internationally famous singer is Enrico Caruso (1873-1921), an Italian operatic tenor. He achieved immense popularity and acclaim during the early 20th century, thanks in part to his recordings and performances that were distributed widely through gramophone records and radio broadcasts.
As recording and communication technologies continued to advance, other singers gained global fame, including Frank Sinatra, Elvis Presley, The Beatles, and Michael Jackson, to name a few. These individuals became household names and cultural icons, reaching a level of celebrity and recognition that transcended geographical boundaries.
