Does anyone know where I can find free episodes of Doctor Who (new and old), if so that would be so much help. Thank you to all that answer this question.

You can watch Doctor Who specials, 26 seasons, most kamakailan 5 series, Sarah Jane Adventures, Torchwood, and miscellaneous other Doctor Who shows (such as pilot episode of K9 and Company)

If you'd like to download them ,all episodes are avilable via torrent. Just go to site like link & paghahanap for the series you are interested in.
