Background on Doctor Who

Before today, I had never watched a Doctor Who episode and was pretty confused before I looked up basic information about the series. I don't know if anyone else was also unfamiliar with it, but I decided to post what I found in case it helps anyone! Doctor Who is a British science-fiction TV produced by the BBC. It is listen in Guinness World Records as the longest running science fiction television show in the world, and as been titled the most successful science fiction series of all time, based on broadcast ratings and DVD/book sales. The show revolves around the adventures of the Doctor, a time-traveling humanoid alien. He explores the universe in his TARDIS (Time and Relative Dimension in Space). Each episode is based on him and his companions working to help people and save civilizations. 11 different actors have played the Doctor. The original series ran from November 1963 to December 1989, but has various spin offs and revived series that began in 2005. The show is now viewed as one of the most influential factors on British popular culture, and is still selling a remarkable amount of DVDs and books worldwide. Hope this helps!
