7. Infamy and notoriety

Infamous is not a fancy way of saying famous. It means quite the opposite: famously wicked or bad. Churchill was famous; Hitler was infamous.

　　Likewise, notoriety doesn't mean just being widely known—it means being known for being bad （though in British as opposed to American usage this distinction doesn't hold）. Calling someone with a record of hefty contributions to charity"a notorious altruist" is a gaffe.

WRONG RIGHT
Although point-of-sales (POS) equipment was introduced over two decades ago it is only now receiving the notoriety it deserves.
