“There are two giant entities at work in our country, and they both have an amazing influence on our daily lives. . . one has given us radar, sonar, stereo, teletype, the transistor, hearing aids, artificial larynxes, talking movies, and the telephone. The other has given us the Civil War, the Spanish-American War, the First World War, the Second World War, the Korean War, the Vietnam War, double-digit inflation, double-digit unemployment, the Great Depression, the gasoline crisis, and the Watergate fiasco. Guess which one is now trying to tell the other one how to run its business?” said a sign that hung at AT&T headquarters in New York before its breakup in 1982.
