You picked an interesting day to hear about Dr. Who- today is the 50th anniversary of the first episode there’s a marathon running on BBC America with the 50th anniversary episode airs in about 5 hours. My 10 and 16 year old are bouncing off the walls waiting for it. I grew up with #4 and #5, and my kids are fans of #10 and #11.
Back in the day, no one expected the show to have the longevity or the following it has, and early episodes weren’t carefully archived.
I started watching the Sarah Jane Adventures, which were Saturday morning children’s programs based on The Doctor and alien adventures.
I didn’t realize at the time that Sarah Jane had been a ‘companion’ in many of the old b/w versions of Doctor Who.
The Saturday morning programs were fun. Many of us missed Elisabeth Sladen who died during the 5th season of The Adventures.
