This is CNN & Other Stories

It's one of the world's most famous words. That deep, confident voice that has grown to become one of CNN's trademarks. I always assumed the voice belonged to a white guy. (I was wrong. James Earl Jones is of Irish, Cherokee and African-American heritage)

The most famous [CNN] ID is a five-second musical jingle with James Earl Jones' simple but classic line, "This is CNN." Jones' voice can still be heard today in updated station IDs. - Wikipedia

His story is amazing:

James Earl Jones possesses one of the most instantly recognizable voices in entertainment history: a commanding basso profundo with a built-in echo chamber that is the very sound of authority. Jones' great range as a performer has made him a legendary American artist. He is a major classical stage actor-his performances as Lear and Othello are towering achievements.....Surprisingly, Jones suffered from a severe stutter as a child, which left him virtually mute. The remedy he found for his affliction was acting. As a child, he was estranged from his prizefighter father and raised by his grandparents on a farm in Michigan. His early years were lonely; he was quiet around other children, self conscious about his speech problem. At the University of Michigan, where he went to study medicine, he began to develop his voice with acting lessons. His rapid improvement gave him an appetite for further theatrical experiences, and soon he quit medicine to devote his attentions to the theater.
