Since LCDtechnology was not yet developed at the time, the TV used a minuscule vintage CRTwhich set the record for being the smallest CRT on a commercially marketed product.
Later in 1982, Sony also released the first model of the Watchman; a pun on Walkman. It had grayscale video at first. Several years passed later, a color model with an active-matrix LCD was released. Nowadays, some mobile phones have integrated television receiver ability and feature. With this idea come the innovative and hi-technology Portable Televisions.
