Holiday Shopping: What to Look for in a TV

So you've finished all of your Christmas shopping and you've got just enough room on the card for that new TV? Before you run out and get the latest and greatest thing, you'll want to check out this decent article at StLouisToday.com. The article starts:

All of us grew up on analog TV; the first black-and-white broadcasts appeared in the 1920s, with color programs coming in the 1950s. But analog is, basically, a radio signal, and radio signals vary in strength. That’s why, for example, you still hear hiss even on the clearest radio program, or see flecks of “snow” and double images on TV shows.
Digital signals are transmitted using computer code, thus reducing broadcast interference. They also take up less space, or “bandwidth,” on a particular frequency, allowing room for several broadcast channels, instead of just one.

We might have stayed with analog if not for computers. Because we sit closer to computers than TVs, computer monitors have higher “resolution” — more dots or minute lines making up a particular image — to minimize eye strain. Now, with more people used to the better images on their computers, they want the same on their TV.

Overall, this is a pretty decent article to get you started looking for that new TV.
