Baseball broadcasting traced from its dots-and-dashes ... In Italy, a boy named Guglielmo Marconi discovered ``wireless'' - he began sending the dots and dashes through the air, without any limitations by connecting wires. The first public usage of wireless was in a sports event. In 1899, an Irish newspaper, the Dublin Daily Express, had Marconi take his equipment to sea to cover firsthand an important yacht race, the Kingstown Regatta.
