As most of you know, this past Saturday saw television history being made. At 19:50 GMT (Greenwich Mean Time, also the time in London, England) the BBC television network held the world's largest simulcast of a television program in broadcasting history. All across the world people turned on their television sets, and a few select groups piled into movie theaters, and saw "The Day of the Doctor", the 50th anniversary feature-length episode of the television series Doctor Who. For many of us, this was the culmination of years of anticipation and speculation. Who will return?
