Because it had so many more advantages than than analogue radio and tv. It has better sound quality, less interference...
It will work with the channels that have switched to digital, but unless your converter box can take in both analog and digital, you will have to wait for the analog ones to switch.
In a analog transmitter the RF carrier have to be modulated with the analog signal either by AM or FM where in digital transmitter the carrier is simply switched on and off a off = a zero and on = a one
An DAC convert digital signal to analog signal i.e Digital to Analog Converter. An ADC convert analog signal to digital signal i.e Analog to Digital Converter.
by analog to digital,digital to analog signal
Digital
Analog instrument are interface with digital instrument with the help of analog to digital converter(ADC).ADC converts analog signals to digital signals.
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.

There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
Analog gauges do not use digital numbers or digital displays. Analog gauges use dials or a pointer. Think hands moving around a dial as in an analog speedometer. If it has digital numbers then it is not an analog gauge it is a digital gauge.
