How Home Theater Works
Until recently, the best way to watch a movie was to go to a movie theater. The introduction of VCRs made it easy to rent or buy movies and watch them at home, but TVs just didn't compare to movie theaters' huge screens and surround-sound systems.

Now, more and more people are turning their ordinary TV rooms into home theaters. This used to involve a projector and a screen, and it was too expensive for most people to afford. But advances in technology have given people more choices for home theater setups, and some people find that a home theater is quieter and more convenient than a movie theater -- and the picture and sound are great.

What Is Home Theater?

Home theater is difficult to define -- it's really just a vague term for a particular approach to home entertainment. Generally speaking, a home theater system is a combination of electronic components designed to recreate the experience of watching a movie in a theater. When you watch a movie on a home theater system, you are more immersed in the experience than when you watch one on an ordinary television.
