Sales of HDTV sets in the U.S. are predicted to total 16 million in 2007, boosting the HDTV universe to 52.5 million, according to the Consumer Electronics Association. The CEA’s new study, “HDTV: You Have the Set, But Do You Have the Content?” found that 30% of U.S. households currently have an HD set and of these, almost a third own more than one. However it revealed only 44% of HDTV owners receive HD programming, as cost and lack of interest were cited as the main reasons why consumers opted not to receive high-def programming. Meanwhile, more than three-quarters of U.S. consumers say their next TV will be an HDTV, according to a survey conducted in May by KRC Research, commissioned by Hitachi America. But nearly two-thirds of respondents said they’re not comfortable in explaining the differences between different types of HDTV technologies, such as DLP, LCD and plasma. Nearly half the households in the survey reported that women are either equally or more responsible for researching major electronics purchases. And more than a third said they would prefer a screen size of 50 inches (127 cm) or larger.
