That's actually quite a lot for back then. The 'pro' choices of the day were basically (studio) videotape[1] for TV and film[2] if you had something really important. While there were lots of people (gadget geeks mainly, I would bet) recording silent and shaky 8mm home movies at the time, 'professional' video recording was used sparingly due to the investment (money, time and people) required. The home VCR didn't happen until the mid-70's for those willing to shell out some serious money. It wasn't until the 80's that it became a mass market item due to affordability which is why you can find so much more video preserved from the 80's and after uploaded to YouTube. [1] It was expensive enough at the time that it was often recycled (recorded over) after whatever show it was for was aired rather than archived. [2] Also expensive and is a write-once medium so used even more sparingly.
