		<description>Hi Dan,

Sorry for the delayed response.  You&#039;re right -- RTB will certainly slow down the adserving process.  That being said, it&#039;s *far* more efficient for two adservers to communicate together than an end-user to two different serving systems.  Will write more on this topic.

		<description>Interesting. It would be nice to see something like this working at scale.

In your second diagram you show the interaction between the publisher adserver and multiple networks. Does this potentially multiple source back and forth not slow down the adserving in the same way a series of dumb redirects would? Especially when you consider that presumably if Network 1 came back with the best price out of 3 or four networks, once the publisher ad server knew that it would need to go back to it and request the actual ad again. It would be interesting to see some realistic HTTP traces for this stuff.

Also, for cookie based ad systems, per request visibility of the user to a behavioural network in this model would be harder to attain, no? The network in this case would need to &quot;touch&quot; the user in order to read the cookie.</description>

		<description>[...] Getting down to brass tacks, Nolet gives an explanation (with graphics) of the efficiencies that real-time bidding (RTB) will offer advertisers and publishers through the exchange model. He takes exception to a part of a recent announcement by Right Media who said they&#039;ve had an RTB solution for a while now. Nolet writes that RM &quot;has not yet been accepting real-time bids from third parties. That being said - it sounds like they’re working on it.&quot; Read more. [...]</description>

		<description>Mike,
Great summary, looking forward to Part II.  At PubMatic, our view is that RTB will be a key part of the future online advertising ecosystem and we&#039;re making it a reality for our publisher partners today.  We real-time enabled our entire publisher platform back in January of 2009 and are working with about a dozen early innovators in this space (including you!) to bring better monetization for our publisher clients and better ROI for media buyers.  

It will be some time before RTB reaches scale within the industry but we&#039;re looking forward to this new(er) approach to monetization.
