Yes, fully aware of the revived doctor thingy. 
Hi Eric. I didn't mean to imply you were unaware of the long Doctor Who history. It was a response to Cheeky Girl's post.
To address another post you made after the one I have quoted: tracking down the earliest Doctor Who is tricky. Many of its earliest episodes are lost to the ages because the BBC, like many international networks of the time, recycled their video tapes, which at that time were on huge 2 inch reel-to-reel platters and were pretty expensive. Some episodes only survive on Kinnescopes, with some done rather crudely by fans. Then there are a bunch of stories that have survived intact and in mint condition, like, "The Daleks." I forget the whole story, but one storyline only survives thanks to an Australian fan who used their 16mm camera and did an improvised kinnescope of a show when it was broadcast there.
I think the "beeb" realized the errors of their ways by the time the Tom Baker era was underway. One of his adventures, "Shada," was never completed. It was scripted by Douglas Adams and was shut down during some kind of strike. About three quarters of it was completed. By the time the show resumed production they moved onto another story. Pieces of that aborted shoot ended up in the Peter Davison "The Five Doctors" story. Sometime in the late eighties or early nineties the BBC brought Tom Baker back to host wrap around segments that connected the surviving "Shada" footage and they released it on home video.
Things will also get complicated if you decide to watch its spinoffs. K-9 & COmpany was a one-off that took the Pertwee/Baker companion Sarah Jane SMith and paired her with the Baker era robotic dog, somewhere in the British countryside. TOrchwood is an incredibly lame spinoff that feels like the revival producer's attempt and mingling his Queer As Folk fan following with his Doctor Who following and comes up with a science fiction Beverley Hills 90210 that is an utter waste of time. Davies did this at the expense of a few episodes of the Doctor during seasons 2, 3 and 4 of the revival It also cost the revived Doctor Who it's best companion in Martha Jones.
The animated Doctor Who Adventures was actually decent even though it was aimed at kids, and what I've seen of The Sarah Jane Adventures has been charming, but that too is aimed at kids. The BBC avoided the mistakes of K-9 & Company when they gave Elizabeth Sladen her second spinoff.
So, run with the Doctor, don't bother with Torchwood, and follow the SaraH Jane Adventures at your own discretion.
