Budweiser created a moving commercial after the September 11th attacks.  Anheuser Busch paid to only run the ad once, during the 2002 Super Bowl.  The company didn't want to benefit financially from the commercial - they just wanted to acknowledge the tragic event.  It gave me chills and made my eyes tear up.

The commercial was then remade on the 10th anniversary of 9/11, showing One World Trade Center (formerly Freedom Tower) under construction in the background
