Most Profitable Internet Niches?

[Matt]

Hey!

I was just wondering what the most profitable Internet niches are.

I know,

"makemoneyonline"
"Weightless"

But what else is valuable?

Thanks in advance!

A profitable niche that your are most well able to serve.
No use to identify a huge market that is profitable that you cannot reach!

Unless you mean in theory and academically - in which case the answer is still the same.
