* Close to one in four (28 percent) of HDTV owners reported they did not get any special equipment from their service provider to watch HDTV channels because the picture quality was already improved with the purchase of an HDTV.
* 23 percent of HDTV owners did not invest in special equipment to watch HDTV channels because a message at the beginning of programs they watch tells them that those programs are being broadcast in HD.
* Nearly one in five (18 percent) reported they believed the HD television would give them high-definition channels without additional equipment.
