His most notable achievement is reviving and running the science fiction series Doctor Who after a sixteen-year hiatus, with Christopher Eccleston, and later David Tennant, in the title role of the Doctor. Davies's tenure as executive producer of the show oversaw a surge in popularity that led to the production of two spin-off series, Torchwood and The Sarah Jane Adventures, and the revival of the Saturday prime-time dramas as a profitable venture for production companies. Davies was awarded an OBE in 2008 for services to drama, which coincided with his announcement that he would step down from as the show's executive producer with his final script, The End of Time (2009–2010). Davies moved to Los Angeles, California, in 2009, where he oversaw production of Torchwood: Miracle Day and the fifth and final series of The Sarah Jane Adventures.
