Pull out the AV receiver in the surround-sound system and turn it around to inspect the back of the component. Look for a connected black box labeled with the name of the audio-captioning service plugged into a set of inputs on the rear of the receiver.
Richard Nixon in 1971. The Nixon shock was a series of economic measures undertaken by United States President Richard Nixon in 1971, the most significant of which was the unilateral cancellation of the direct international convertibility of the United States dollar to gold.
We had lost most of our reserves by the time Nixon pulled the plug in 1971. What most people think of as a gold standard, that the US ever had a stable, long-term, full and open pegging of the dollar to a redeemable amount of gold, is a myth. There was never a time where the central bank or government had an amount of gold or silver equal to our currency.
