The 1990s then saw Sony coming through with their best-selling television, which featured the best screen with a dual speaker system. It also had a headphone connect jack for external speakers and other audio-video cables outputs. All this played an important role as this was also the gaming period; therefore, the jack made it possible to connect consoles.
