Now we all know advertisers are hard pressed to attract the attention of message-weary consumers but we never thought they’d take to literally clobbering people over the head to get them to pay attention to their ads. This past Wednesday around 2:30 PM, a piece of a large L’Oreal billboard in Toronto’s Eaton Center fell and hit a man seriously injuring him along with two others. High winds, versus an aggressive guerrilla media planning strategy, were blamed for the incident. Local TV report here.
