Is TBC Classic any popular?

I played Classic when it first launched and it was awesome. Thousands of players around everywhere and everyone was just so excited to play it. Before it launched the anticipation was huge. But what about TBC? I remember seeing the reveal video and no one really seemed to care. I never really ever heard anyone talk about it. I didn't even know it came out until like 2 months later after it did.And now I just discovered you can buy boosted characters in TBC. So is Classic dead and does no one really care about TBC?
