 Yes that's how Google and DoubleClick and just about everyone else
serve ads to other people. It is *not* how Yahoo! inserted ads into their
own AJAX heavy front pages, it is probably not how Google insert ads into
their own pages, but of that I have no direct knowledge.

 Nobody said anything about static ad images - these things are
widgets injected complete with HTML, CSS and JavaScript.

 Yes yes yes - that's why the ad server was such a beast. It
locates a suitable ad based on the user's data, satisfying all the dozens
of contract terms and standards about how often the same ad or ads in the
same group may appear to the same person and a whole bunch of other stuff
and then provides the HTML with all the tracking baked in for the webserver
to inject where the marker is. It does all of this in an obscenely short
time.

 I was talking about Yahoo! Who do their own thing and like to run
their own spyware.
