The Tyler Public Library is celebrating the 50th anniversary of the popular science fiction series “Doctor Who” now through Sat., Nov. 23.

Programming will include a trivia quiz, episode marathon and costume contest. “Doctor Who” first aired on the British Broadcasting Corporation on Nov. 23, 1963. The series follows the adventures of an enigmatic alien, the Doctor, and his companions in their fantastic travels through time and space in a spaceship called the TARDIS (Time And Relative Dimension In Space). The series aired for 26 seasons, but was cancelled in 1989. In 1996, FOX network attempted to bring the series back in a pilot TV movie continuing the Doctor’s adventures.

The prospects of a new American series failed and it was not until 15 years later, in 2005, that the series returned on the BBC. The new series combines the continuity of the previous series with the TV movie and has become a world-wide sensation.

“‘Doctor Who’ is such a remarkable series that tackles serious themes in a manner that is engaging and entertaining,” said City Librarian Mary Vernau. “This series has not only shown its durability on television but in a variety of other media, including books, audio books, comics and radio programming. The Tyler Public Library is happy to celebrate this occasion with the public.”

The trivia will run from Nov. 4 through Nov. 20 and will culminate in a raffle for a special prize. On Saturday, Nov. 23 there will be a “Doctor Who” marathon from 11 a.m. to 3 p.m. and the costume contest will start at 3:15 p.m. in the Library’s Taylor Auditorium.
