You didn't specify audio or video, but I guess the answer is pretty much the same. Digital allows for more information to be encoded into the signal. In video that can translate into more lines of resolution for a high definition image. There can also be other layers of data for interactive capabilities.
In audio it allows for a more precise translation of the original sound, plus the ability to encode multiple channels of separation. That is how home theater sound systems decode DTS & Dolby 5.1 (5 channels of audio plus subwoofer).
Analog simply cannot deliver these levels of descrete detail. What analog audio does have is some signal smoothing that makes the sound very warm and rich. Analog video really has no advantages over digital video.

Analog is what we have now for TV and radio. Digital is what is being introduced over the next few years. Digital signals are either perfect clarity or nothing at all. There is no in between. Analog, as we know, can be distorted, ghosty, snowy, etc. The problem with digital is that is has a limited range. It is perfect clarity for a certain distance, then nothing. Certainly worth thinking about before investing any money into it.
