How many times have you been caught somewhere and wished that you had a portable TV with you? Trips to the airport, long car trips, long stays in a waiting room--all of these could be made a bit more tolerable with a portable TV to fill the time. The portable TV is not a new invention. What is new is the technology with which the portable TV has become a fine-tuned instrument of entertainment and information.

The Evolution of the Portable TV

Years ago, it was possible to watch broadcast television on a tiny battery-powered screen. The image quality left something to be desired, though, and it was very difficult to tune in to the exact station for which you were looking. For yours truly, this often led to a feeling of ambivalence, in which I knew that I wanted to watch a program, but maybe I was better off leaving it alone than watching a static-filled series of lines and squiggles.

Thanks to numerous advancements in technology, the experience of watching portable TV has been escalated to a tolerable, even enjoyable pastime. For starters, the flat panel displays that provide crisp clear images on computer monitors and larger televisions provide a phenomenal medium around which the portable TV is based. No longer is the portable TV dependent on a small picture tube.

Other advancements in signal technology, including satellite and digital technology, have allowed for a number of possibilities in watching portable TV. A number of manufacturers make dedicated portable DVD viewers, which are essentially portable TVs with a built in DVD player. The variations of portable TV-style devices increase each year, and new innovations are integrated with each passing model.
