We may compare Panasonic to the character of Michael Myers way too often, but this Halloween the analogy is particularly relevant given news the company is officially killing plasma TV production. Manufacturing of plasma panels will end in December this year, earlier than the most recent rumor suggested, with the last remaining factories going dark in March 2014 at the same time sales efforts will cease. It's a strategic decision to free up resources, the firm claims, citing low demand for plasma and the impact of LCD development as reasons for its exit. "Severe price competition" as a result of the Lehman Brothers collapse way back in 2008 is also blamed, so when you're left wanting the warm glow of new Panasonic plasma next year, you know who to shake an angry fist at.
