Since last 53 years we are using push buttons on phones, specially the landlines. But do you know when was the first time that these push buttons were used ?
It was today in 1963, that the first electronic push-button system with touch-tone dialing was commercially offered by Bell Telephone to customers. The push-button telephone is a telephone that uses buttons or keys for dialing a telephone number to place a call to another telephone subscriber. It was installed first in Carnegie and Greensburg, Pennsylvania, just outside of Pittsburgh.
The push-button phone replaced the rotary dial phone, which had been in use for decades.
On the rotary dial, the digits are arranged in a circular layout so that a finger wheel may be rotated with one finger from the position of each digit to a fixed stop position, implemented by the finger stop, which is a mechanical barrier to prevent further rotation.

1963 में आज अमेरिकी टेलीफोन कंपनी Bell System दुनिया के सामने पहला ऐसा फोन लेकर आई थी जिसमें Push Button वाला Dialling Pad था। इस तरह के फोन को पहली बार पेनसिल्वेनिया में लगाया गया था। उस दौर में ज़्यादातर लोग rotary dial वाले telephones का इस्तेमाल करते थे।
