This is a useful resource that I've never seen before. It shows the sad decline of Aikido in popularity. Also the word martial arts, is not so popular any more, but MMA and UFC are on the rise.
I guess it's just what's in the media, it's a big factor.
wow aikido + UFC = 100% on the trend graphs ('cept its normalised scale so not really true)
Some might say Aikido is an early MMA, being a gendai sogobujutsu, just need to get ourselves a cage and rebadge
