It looks like high-definition television is steadily becoming the norm in American households.
Nielsen reports that as of November 30 HDTV penetration reached 23.3% of US homes, coming a long way since the company began tracking the stats in July 2007 when that number only sat at 10%.
Lower prices and increased availability of HD programming, along with the planned transition from analogue to digital broadcasting in February 2009 are fueling State-side sales.
Washington, D.C. has the highest HDTV penetration, with 31.1%, followed by Boston and New York with 30.5% and 30.2%, respectively. Detroit has the lowest HDTV penetration at 20.9%. Sporting events have the highest index of viewing in HDTV households, with HDTV receivable and capable homes watching 54% more sports than non-HD ones, followed by political programming (25% more popular) and awards shows (10% more popular).
