In a statement, Samsung credited Garrihy for his "unwavering commitment and passion, and for the part he has played in helping us dramatically improve our brand value whilst also delivering an outstanding Olympics activation".
Garrihy led a 35-strong marketing team, which was swelled by an additional 20 freelance staff during the Olympics, and was responsible for the entire Samsung range, spanning mobile, TV, digital imaging, white goods, IT and B2B.
Samsung added that "marketing is much stronger" following his two years at the company.
