U.S. Census Bureau Daily Feature for Nov. 3 | Reuters: "PBS, the Public Broadcasting System, aired its first television broadcasts 40 years ago today, as a string of local educational channels united to form the network. Over the years, PBS has built a reputation for excellent programs and objectivity. Some of its well-known programs include the NewsHour with Jim Lehrer, Masterpiece, Antiques Roadshow, The American Experience, and Sesame Street. For some years, it was the leading broadcaster of key tennis matches. The Public Broadcasting System currently has more than 350 stations, which collectively own the network."
