Step 1 : Introduction to the question "When did the Cable News Network (CNN) first launch?"
...Cable News Network (CNN) debuted at 6 p.m. EST from its headquarters in Atlanta, Georgia. It was June 1, 1980. The lead story of the debut show covered an assassination attempt against civil rights leader Vernon Jordan. With its debut, CNN ended the unspoken rule that news could only be reported during certain fixed hours of the day. It was initially available in less than two million U.S. households. It's competition at the time was the three networks - NBC, CBS, and ABC - who broadcast news in 30-minute shows each night. CNN broke that mold and changed the world of broadcast journalism.
