Let’s take a trip back in time! Can you name the pioneer who kicked off the radio era?
I’d go with Reginald Fessenden and his 1906 Christmas Eve voice/music demo, often cited as the first true “broadcast” (Reginald Fessenden - Wikipedia). If you mean Morse-only, then Marconi beats him by years — first pitch vs. first home run. Are we talking first voice program or any wireless signal?
