Paintball as we know it began in the early 1980s, so it is still a pretty recent phenomenon. Information about it in the 1980s was sketchy in my neck of the woods. How did you play? Did it hurt when you got shot? I had so many questions and no answers. No one in my group of friends played and before the internet, that was pretty much the end of your knowledge search unless the subject was popular enough to show up in a book or magazine.
This commercial from 1987 shows the sport while still in its formative phase. It is the type of subdued information style ad that leaves a lot to the imagination and would have gotten me very interested in giving it a try.
