QUESTION: I've been playing around trying to create something that looks like this cool retro intro to ABC's Sunday Night Movie. The way the text streaks has be a bit bamboozled. Is this slit scan? An old school digital effect?

"Digital 3D" motion graphics didn't really become "the cool thing" in broadcast till about 1984, though the first digital visual effect was in the film "Westworld" circa 1975.
