What is the market / industry size of online product reviews? ?

I'm looking for some information regarding online product reviews. I understand it's not quite an industry, but I would like some information such as, how big is its revenues, who are the users? Would love to know as soon as possible. Thanks. I know it's not quite an industry because of its size and nature of business. But I'm looking to find some information regarding how much online product review companies are earning, and who the user segments (target market) are. Any clues? Much appreciated.

1. Lol luck on that one, each product has it own review not an over all review.
