 * November - BBC Wales announced that it would produce a new series of Doctor Who for broadcast in 2005, returning the series to weekly television after a sixteen-year hiatus. Named executive producer was Russell T Davies, best known as the creator of the controversial Queer as Folk series, but who also was a long-time fan of the franchise; he wrote a novel for the Virgin New Adventures book series, Damaged Goods. Julie Gardner was also named an executive producer on the series. Little was revealed about the proposed series at this point except that it would be a continuation of the 1963-89 series and not a remake. The immediate impact on Richard Grant's status as the recently unveiled "Ninth Doctor" was not known.
