If you're a history buff, you may be about to lose a huge chunk of your day. In what the AP says is "the largest upload of historical news content" to be placed on YouTube, the agency's newsreel archives and those of British Movietone are now online. The two channels, AP Archive and British Movietone, contain more than 1 million minutes of footage going as far back as 1895 and include the hilarious, the harrowing, the strange, and even cat videos. There's also no shortage of celebrity content, with recently added clips including a 1956 Elvis Presley gig in Tupelo, Miss., the Guardian reports. (More Associated Press stories.)
