Antistatic mouse mats are still a thing to this day
Whilst working for a large retailer's support centre, we were required to state that using a mouse built up static electricity that would disable the mouse over time.
Simply by unplugging the mouse (ps2 not USB) and then plugging it back in again would remove the fault everytime and if they would care to purchase a antistatic mouse mat then the problem would go away for good.
That the manufacturer supplied mouse and ps2 port connectors were copper and aluminium respectively had absolutely nothing to do with the problem. That removing and re-inserting the mouse removed offending oxide layer is purely coincidental, it was really static build up honest.
That this problem existed with manufacturers products for so long that even today you can still buy antistatic mouse mats shows just how credulous their customers were and still are.
