Iain Gray remembers Betamax - even if Sony doesn't.
Back in the 1980s, at around the same time as perms, Pong! and Pat Sharpe, consumers could walk into an electrical retailer and be faced with a choice between two video formats - Sony's Betamax and JVC's VHS.
Each had their merits and flaws but the difference in quality between the two was negligible. So when VHS achieved market dominance and Betamax was confined to car boot sales and charity shops, it was costly blow to Sony.
However, never one to give up, Sony is now heavily embroiled in another format war. This time the battlefield is High Definition home cinema and the company is up against the not-inconsiderable might of Toshiba and Microsoft
