Nowadays many new technologies are being developed. They make it possible for users to control almost anything that is electric or electronic from portable computers or even cellular phones. A working mother can check on her baby's first steps at the day-care center from a laptop on her office desk. Digital photographs of vacations and family events can be uploaded onto the big screen and enjoyed in a room full of people. The "family room" is quickly becoming old-fashioned. In its place, a "media room" is being designed. In face, the home theater is one of the fastest-growing segments of custom electronics.
