As an owner of a marketing and PR firm, I have always been amazed at the PR nightmares large brands get themselves into with expensive ad campaigns that seemed so clueless, ill-timed, and often with a complete lack of common sense. The backlash of H&M's recent "duh" ad featuring a black child model wearing a hoodie with a monkey and saying "coolest monkey in the jungle" inspired me to gather some of the most controversial and unbecoming ads in recent years.
