Since then the network has covered wars, natural disasters, politics and pop culture -- in America and around the world.

Look back at some of the moments that have defined the last four decades.

CNN's Bernard Shaw, bottom left, was one of the moderators for the presidential debate between George H. W. Bush and Michael Dukakis in October 1988. Shaw asked Dukakis, a well-known opponent of the death penalty, if he would support a death sentence for the killer if his wife was raped and murdered. Dukakis's rote answer to such an emotional question -- that he opposed the death penalty because he did not consider it a deterrent to crime -- sounded unfeeling to some. Others criticized the question itself as unfair.

In one of the most memorable moments of a blockbuster murder trial in June 1995, O.J. Simpson struggled to fit his hand into a glove prosecutors claimed he wore the night his ex-wife Nicole Brown Simpson and Ronald Goldman were killed. The prosecution's request to have Simpson try the gloves on in court was a pivotal moment in the trial, which ended with the former NFL star's acquittal.

CNN's Clarissa Ward reports from Aleppo, Syria, in February 2016. The assignment took Ward to places almost no Western journalists had visited in over a year. The team traveled undercover with Ward wearing the niqab, a black veil that covers the entire face except for a small slit at the eyes. "We wanted to see for ourselves what life is like under the bombs," Ward said.
