KTTV is marking 70 years on air.
Since 1949 we've been covering every major event in Southern California from the British Invasion, the death of Marilyn Monroe to the LA riots, the 1994 earthquake and the O.J Simpson trial, we've been there for everything.
Part of our mission with KTTV's 70th anniversary is to revisit and preserve the past.
They're the stories and history of Southern California and you might be surprised just where that historic film is being stored.
Parts of LA's history lies deep underground in the salt mines of Hutchinson, Kansas. Go about 650 feet down and you'll find pieces of Hollywood- old films being stored and preserved in the mines. A few films we found were 'The Wizard of Oz', 'Titanic' and hit shows like 'Glee' and 'Modern Family'. There's storage spaces with over 6 million boxes of valuables.
There's also hundreds of boxes storing four-decades worth of news stories.
