Business 2.0 runs an article (no registration required) about the domain grabbers:

"And you thought the domain grabbers vanished with the dotcom bust. The boom in Internet advertising and the success of the pay-per-click ad model are making the go-go '90s look sluggish. Back then, buying a domain name was pure speculation: Snap up Whatever.com and sit back until some big company with a get-on-the-Internet-at-any-cost mentality offers you a set-for-life payday to buy it.

Now it's all about the income stream. A single good domain name -- Candy.com, Cellphones.com, Athletesfoot.com -- can bring in hundreds of dollars a day, in some cases while the owner hardly lifts a finger. Schwartz, for instance, directs his traffic to one of the many small companies that serve as go-betweens with Google and Yahoo, the two giants that make this all possible. The middlemen, known as aggregators, do all the heavy lifting, designing the sites and tapping into one or the other of the search engines' advertising networks to add the best-paying links. Many other big domainers cut out the middlemen, creating their own webpages and working directly with Google or Yahoo.

No one knows for sure how much Web traffic comes from type-ins, and Google and Yahoo execs won't discuss it. But privately, during one of the late-night parties at the Traffic conference, one Yahoo official estimates that type-ins could make up 15 percent of its search business. Marchex, a Seattle-based public startup whose strategy rests largely on type-in traffic, estimates that it accounts for nearly 10 percent of the global paid search market, which is projected to soar from $9 billion this year to $23 billion in 2009."
