UFO (TV series)
A single season of 26 episodes (including the pilot) was filmed over the course of more than a year; a five-month production break was caused by the closure of MGM-British Studios in Borehamwood, where the show was initially made. Production then moved to Pinewood Studios in Buckinghamshire. "UFO" was first broadcast in the UK and Canada in 1970, and in US syndication over the next two years.
2012 phenomenon
The UFO conspiracy TV series "The X-Files" cited 22 December 2012 as the date for an alien colonization of the Earth and mentioned the Mayan calendar "stopping" on this date. The History Channel aired a handful of special series on doomsday that included analysis of 2012 theories, such as "Decoding the Past" (2005–2007), "2012, End of Days" (2006), "Last Days on Earth" (2006), "Seven Signs of the Apocalypse" (2009), and "Nostradamus 2012" (2008). The Discovery Channel also aired "2012 Apocalypse" in 2009, suggesting that massive solar storms, magnetic pole reversal, earthquakes, supervolcanoes, and other drastic natural events could occur in 2012. In 2012, the National Geographic Channel launched a show called "Doomsday Preppers", a documentary series about survivalists preparing for various cataclysms, including the 2012 doomsday.
