[edit] History
In the 1970s and early 1980s, Panasonic and Sinclair Research released the first TVs which were small enough to fit in a large pocket; called the Panasonic IC TV MODEL TR-001 and MTV-1. Since LCD technology was not yet mature at the time, the TV used a minuscule CRT which set the record for being the smallest CRT on a commercially marketed product.
Later in 1982, Sony released the first model of the Watchman; a pun on Walkman. It had grayscale video at first. Several years later, a color model with an active-matrix LCD was released. Nowadays, some cell phones have an integrated television receiver feature.
Since the switchover to digital broadcasting, portable TVs have reduced in size and improved in quality, the major current manufacturers of DVB-T standard (common throughout Europe) portable TVs are August International, ODYS and Xoro.
