Portable TV

Im a big fan of portable television because I like to watch a lot of TV. Basically its a small device with a small display that can viewed with good quality. Screens usually vary from size,but I believe the biggest they go are probably about 5 inches. Some history about portable TV's is that they were first introduced in the 1970s early 1980s. In 1982 Sony released their first model which was called Watchman. So for those who really like TV Im sure you have one of these. Nowadays cellphones are able to be used as televisions.
