David Sarnoff, then president of RCA and a strong advocate of television, chose to introduce television to the mass public at the RCA pavilion. As a reflection of the wide range of technological innovation on parade at the fair, Franklin D. Roosevelt's speech was not only broadcast over the various radio networks but also was televised along with other parts of the opening ceremony and other events at the fair. That day, the opening ceremony and President Roosevelt's speech were seen on black and white television sets with 5 to 12-inch tubes.[9] NBC used the event to inaugurate regularly scheduled television broadcasts in New York City over their station W2XBS (now WNBC). An estimated 1,000 people viewed the Roosevelt telecast on about 200 television sets scattered throughout the New York metropolitan area. . . . .
