The head of Best Buy had been sitting in the doghouse with investors, as he world's largest electronics retailer struggled to keep up with the hyper-competitive world of online shopping.

CEO Brian Dunn, who rose from sales associate to lead Best Buy over the course of 28 years, resigned in April 2012 after the board began investigating his personal relationship with an employee. Judging by investors' reactions, it appeared they cheered the news but were well aware the big-box retailer face big challenges in the months going forward. Shares rose 3.3% on news before quickly falling 2.3%. Now Best Buy founder and former chairman Richard Schulze is attempting to acquire the struggling retailer.
