The CNN apocalypse video has always been the stuff of legend – a tape that was only meant to be broadcast at the end of the world. It was to be the last "event" CNN would ever cover.

When the news network launched in 1980, founder Ted Turner made a grandiose and specific promise about his newly created round-the-clock operation. "Barring satellite problems, we won't be signing off until the world ends," Turner declared. He also said, "We'll be on, and we will cover the end of the world, live, and that will be our last event. We'll play the National Anthem only one time, on the first of June [the day CNN launched], and when the end of the world comes, we'll play 'Nearer, My God, to Thee' before we sign off."

Many thought he was joking, until January 2015 when the tape was leaked on the internet. According to former employees, an ex-CEO, and a CNN archivist, they've all been trained to use the tape.

Turner, who has since retired from the media industry, has yet to comment on the video's authenticity.

Interesting to note: "Nearer, My God, to Thee" was said by survivors to be the last song played by the band on the Titanic.
