It all started with a billboard in Los Angeles, CA.
In a few days, Audi replaced the billboard with a new billboard which challenged BMW.
As expected, BMW did respond by buying a billboard just across the street.
Audi turned to its Facebook fans and the fans came up with some clever photo-shopped replies .
BMW fans also responded with Photo-shopped replies. One submission is shown below.
Later BMW moved it’s billboard to some other place and the billboard ad war came to an end.
