It has always been something of a running joke here in England, where you have to buy a license from the government in order to watch TV (I kid you not, it helps fund the good old BBC), that blind people get a 50 percent reduction on the annual £135 ($271) fee.
However, in a similar way that subtitles and closed captioning have allowed deaf people to enjoy TV and video output for years, technology is now bringing the same benefit to blind folk.
