My kids like to watch My Little Pony. Can't believe how long it has been around.
I know right? I also can't believe that some grown men are into a girls show and toy line. 
Well those ponies are pretty cute. Rainbow Dash is sparkly as well.
That's true, though their appearances have really changed since they were first made in 1981.
That's when I was born, lol. I remember they were big during the 80's. Now there is much more competition in the toy aisles.
There is a good deal of competition, but it's hard to miss their colorful bodies and manes honestly.
Some cartoons last forever. I wouldn't be surprised if they go another 40 years.
They will probably change a lot like they have already, with the incarnation of things like "cutie marks".
