Michael Botein, a pioneer in the study of communications and media law who loved teaching died Wednesday at his home in South Orange, New Jersey of complications from cancer. He was 71.

Botein was a professor emeritus at New York Law School, where he established the school’s media center in 1977. From there, he was well-positioned to witness a revolution in communications that included the unprecedented growth of cable television and the internet, the advent of broadcast satellites and the breakup of AT&T.
