Nevertheless , the WJZ network sought to compete toe-to-toe with the AT&T network , which was built around a different New York station , WEAF ( today 's WFAN ) . For example , both stations sent announcer teams to cover the 1924 Democratic National Convention , which was held in Madison Square Garden in New York City . Promotional material produced in 1943 claimed certain " firsts " in broadcasting by WJZ , such as the first educational music program in April 1922 , the first World Series broadcasts in 1922 , and the first complete opera broadcast , '' The Flying Dutchman '' , from the Manhattan Opera House
