Retail pro Joe Magnacca

Joe Magnacca, known for revamping Duane Reade’s beauty section—in particular, developing its Look Boutique—which eventually played a leading role in Walgreen’s acquisition of the chain retailer—has left drug stores to bring his marketing savvy to electronics stores. Magnacca now holds the power of chief executive officer at RadioShack, where he has also been named a member of the company’s board of directors.
