Coax cables have been around since the 1920s, but their popularity peaked in the 1950s with the invention of the television.
In 1953, RCA (Radio Corporation of America) developed the first coax cable for broadcasting television signals, revolutionizing the way people watched their favorite shows.
Coax cable was used for both commercial and residential broadcasting, allowing for the first time for people to watch live, over-the-air television.
Today, coax cable is still used in some areas for high-speed internet and cable television connections.
Ralph Johnson is often credited with inventing the first modern coax cable, but his work was actually built upon by Edith Smith, who developed the first coax cable for residential use.
