Sony is no longer an electronics company

Sony announced last night that it's spinning off its audio and video divisions, much like it spun off its television division last year. That won't mean much right now; Sony still displayed interesting new Android-powered TVs at CES, and we're sure to see new crazy high-end Walkmans and camcorders with Sony branding from the newly independent AV division as well.But the long-term reality is far more stark: after years of promising "One Sony," CEO Kaz Hirai appears to be systematically breaking the company up for sale. The VAIO PC division was sold last year and just announced its first hybrid laptops as an independent company, and Hirai told investors that he has to consider spinning off the smartphone business and possibly selling the TV business outright.From one Sony to no Sony.
