The Nielsen Corporation recently released some interesting information on the status of households having HD sets and monitors as of March 2008. They have ordered it into three categories showing percentage of homes with HD.

HD capable and receivable – 15.9%. These are homes that have an HD TV and HD tuner and receives at least one HD network or HD TV station.

HD capable – 20.1%. These are homes that have an HD TV and HD tuner that can receive HD signals.

HD display capable – 28.7%. These are homes that have an HD set capable of displaying HD content. This is a monitor that can be connected to an external tuner such as a cable set top box or satellite receiver.

It looks like HD sets are catching on and purchases will likely increase as we get closer to the analog cutoff date.
