Back when Red & Blue were the only Pokemon games in the states, in that wonderfully nostalgic period of time before life revolved around the internet, I remember learning about how to do the Missingno glitch from neighborhood kids. My neighbor and his brother showed me how to do it. I was 8, they were 9 and 10.
How did people even find out about this glitch in the pre-internet days? Was it ever featured in Nintendo Power or something?
