My column in today's National Post looks at how Sony has fallen from grace over the past three decades. Once a leading innovator, the company's troubles has been marked by technology standard losses (BetaMax), product disappointments (the eReader, at least so far) and missed opportunities (the MP3 player). The latest stumble is a huge battery recall that will cost Sony more than $225-million and an untold hit to what was once one of the world's respected brands.
