Nikola Tesla was granted the first radio patents in 1900, resulting in Guglielmo Marconi’s initial radio patents to be denied that same year. Four years later, the U.S. patent office reversed its decision and awarded Marconi the patent for inventing radio, despite the fact that Marconi’s devices used 17 of Tesla’s patents. In 1943, the U.S. Supreme Court upheld Tesla’s original patents, but the history books had already recorded the name “Marconi” as the inventor of radio. In 1920, the world’s first commercial radio station, KDKA, went on the air in Pittsburgh. FM Radio made its first appearance in 1939.
Now 62% of shoppers are listening to the radio an average of 14 minutes prior to shopping.
