CNET reports that Tetris has been around for a quarter of a century.
According to the Commerce Department, during that time the world lost approximately $423 trillion in productivity due to people playing at work. This amount is surpassed only by Microsoft Solitaire and Freecell, which have combined to destroy $487 trillion in global output.
"Everyone wants to blame the banks, Wall Street and General Motors for the worldwide economic crisis," said Commerce Secretary Gary Locke. "But when you stack all that up against nearly a quadrillion dollars in economic destruction, credit default swaps are like single-A baseball, at best. Tetris alone has negated all business output since Neanderthals started trading bones with each other. That's impressive."
The Commerce Secretary added that he expects Facebook to surpass them all by next Tuesday.
