this is an 80s phenomenon. i was not there, so i can't tell you what the reality of it is. i can tell you what was intended and what i believe happened.
in 1985, owning a video camera was not unusual. being able to edit video was something almost no consumer could do however, and nonlinear editing like we have now did not exist outside of multi-billion-dollar corps
a) applying overlays on analog video was pretty fuckin hard and iffy to begin with
b) the amount of memory needed to store a reasonable typeface or frame buffer was still quite expensive
1) why was this such a big deal? there were thousands of them. i've never seen what they did. could it possibly have looked good, and not cringeworthy?
2) they put them in odd places
please enjoy some Titled footage from @narunetto, created with the videonics tm-3000. i doubt this is representative of typical consumer titlers, but it is funny
