Oh, I know it's still around. It's just that here in the US, it seemed like NBC was constantly pimping the short track stuff, while one had to seek out the long track to even know it existed.
As to why they'd tout Ohno so much more, I'm agreeing with you. I guess they saw Ohno as more of a "star"... Maybe it's the past medals, or the crashing and increased level of controversy in his events, or something. Probably the latter the way they present things now.
I just think the long track is great stuff. I'm not a winter guy, but those guys are incredible athletes. They probably deal with as much lactic acid as anyone.
