Here is the famous commercial Budweiser produced after 9/11. They aired it only once, at the Superbowl in 2002. Anheuser Busch stated they wanted to acknowledge the event, but not to benefit financially from it. Note that in the commercial, the World Trade Center is gone.
I never saw this commercial until now… I was surprised as to how moving a beer commercial could be.
