i remember when my little pony made it's comeback. i signed the petition to hasbro in 1995-96ish to bring back the line. it's a perfect example of the underground coming to the foreground. because we were trading and buying and selling the old ones from the 80s and wanted a revival.
it didn't last long, that time. people weren't happy with the 2nd generation. but right about when it was done selling in the USA, 1999 or so, hot topic started to sell merch.
the third generation that's out now, seems to be doing okay... and look at this:
it's a big deal... i have the original six from when i was a kid. this is a set being released this month to celebrate 25 years of my little pony... i feel old.
