It would not appear that digital television has changed the world, yet.
The digital standars in the U.S and other parts of the world had digital television in the early 1990's although digital television broadcast did not begin until later on.

The move to digital television broadcasting reflects the change in production, storage and viewing of television content. Digital transmission adds features that analog services are unable to support and there is a flexibility in the use of transmission bandwidth that is also not possible with analog broadcasts. As far as the viewer is concerned, digital television broadcasts allow far more channels to be received and normally with better image quality than seen with analog.
If you mean 720 to 1080, If the TV is capable of 1080, it's done automatically in the TV set.
The time it took to change analog television signals to all digital took about 25 years. It started around 1986 and many television stations had converted over to digital signal by the year 2010. Persons who owned analog televisions had to either buy a new digital television or use a converter box to get a clear signal.
Only if you have a digital output on your cable box. If not, it'll end up being a digital signal, converted to analog and then reconverted by your TV back to digital. Besides, the digital changeover date is only for local television stations when they turn off their analog transmitters. This means that if you currently have cable or satellite with analog outp[uts, that aspect of it shouldn't change.
The signal sent to the TV must be a digital signal as well.
Actual televisions won't be affected by the digital signal change. What matters is what reception tool is used (e.g. cable, satellite, antennae). Television antennae will not work when all television is transmitted using digital signal. If you have cable or satellite though, you have nothing to worry about.
