What are the "major" MMA organizations out there?

I've seen UFC heard of K1, and was told about Pride here. Are those the major ones, or are there others?

Pride is hands down the best
UFC
WEC
K-1 had Romanex MMA but it's called off from what I understand.
King of the Cage
2H2H (2 hot 2 handle)
Sometimes there is an Inoki Bom-Ba-Ye in Japan

those are some of the bigger ones
