I'll chime in here to add The Day the Universe Changed, on PBS. Less "invention" specific and broader, about how certain concepts shifted us. It has also aged better, in my opinion. Connections, especially its last episode, seems rooted in a certain place and time.

All of those Connections shows with James Burke (Connections, Connections^2 and Connections^3) were totally phenomenal to me when I saw them and absolutely sparked my interest in inventing. I still occasionally watch the original Connections series, having downloaded them to my collection.
