Animation used for Ebay and Amazon

The animation for Ebay and Amazon was hard to find.  For Amazon I went to view, view source using the school's Mac computers and I could not find a animated gir or flash animation to save my life.  Amazon uses a flash animation which is an AD for bank for America.  Ebay did not have any form of animation because there was already enough happening on their page and there was zero animated advertisements like Amazon.  The Ad on Amazon does not continue continuously.  The viewer roles the window down for the dog and he sticks his head out the window.  The Ad is located near the bottom of the screen and i could barely notice it with all of the great products i could buy right in front of me.
