Organic will assume interactive duties for Bank of America, which just awarded its advertising account - valued at around $600 million - to Omnicom, reports ClickZ. Eight Omnicom agencies will divvy up the work. Omnicom EVP Susan Smith Ellis gave credit to Organic for its part in the pitch. "Organic did a tremendous job, they added real value in adding smart strategy overall, not just online," Ellis told ClickZ.
