how is this company worth $50m?, page-3

Its because Carsales.com has its own "self service ad platform". Its called MediaMotove. Go to their website and click "Corporate Advertising" at the bottom:

http://www.mediamotive.com.au/
http://www.mediamotive.com.au/industries/

I fail to see how this "self service ad platform" is anything revolutionary and why Carsales.com, Realestate.com can't just (or won't eventually) do that themselves. And not pay any fees to anyone.

The other thing is, if you are a publisher, you can just install OpenX.com on your site (Which is FREE) and it has 90% of the features of Adslot.

I challenge anyone to explain to me why Adslot is a better solution than OpenX.

Please I'm waiting.
