Standard, or analog, television has gone by the wayside and made space for high definition television (HDTV) to entertain millions of viewers in the United States. High definition television means that televisions will need to be able to display the programs in widescreen format. This is because true HDTV is broadcast in widescreen. The widescreen, true HDTV, allows for a higher resolution picture and also the increased quality of the broadcast contains improved audio capability. Alas, in order to take advantage of the true HDTV signal feed, you may need to purchase an HDTV tuner.
