In a breakthrough that would change the face of communication, Guglielmo Marconi stood atop Signal Hill in St John's, Newfoundland, eager to prove his groundbreaking theory. With his trusty equipment at the ready, he waited anxiously for the signal to arrive from across the Atlantic. And then, it happened - the letter "S" in Morse Code, transmitted from Poldhu in Cornwall, England, crackled to life on his receiver, sending shivers down his spine. This monumental achievement marked the first time a radio signal had bridged the vast expanse of ocean, paving the way for modern global communication.
