Where do Internet Ad Servers Fit?How do they work? • Think of the CGI model, but with the server delivering ads to an Image box • i.e. Page contains an ad container • <IMG SRC=http://adserver.com/?cookieinfo> • Cookie info is information collected about this user locally • Browser reserves space for an image • Get request gets sent to ADSERVER with whatever relevant local information is available (at a minimum, the IP Address) • ADSERVER combines info from the user with other information it has. • ADSERVER runs an on-line auction to determine what ad to serve • ADSERVER serves up an “appropriate” ad and sends it to the browser. • ADSERVER now can identify who got the add and what the response was • Completely new way of delivering and measuring ads. • Developed by Double Click in 1998, DC eventually bought by Google for $3.1 billion • Formed a whole new industry.
