Around 1990 somewhere, I realized I lived near the resource center for the school district, and I went and asked if they had any of the Bell Science Series sitting around. They didn’t. Then one of the public domain cable channels had a slot for them for a while—a very short while. I tuned in in the middle of one, and they maybe showed one more before putting something else in the slot.
Now you can find them on YouTube, of course. I think I’ll be downloading stuff for a while, folks. Pardon me.
