HD Viewing Lags Behind SD
While HDTVs are now in more than half of U.S. homes, less than one fifth of TV viewing is viewed on an HDTV on an HD channel through an HD channel. That's according to numbers released this week by the Nielsen Company.
The survey found that while HDTV is in 56 percent of U.S. households, only 13 percent of cable and 19 percent of broadcast viewing is truly in HD. This is because 44 percent of viewers do not own HDTVs, many who do own non-HD sets in addition to their HD sets and some watch SD channels on HDTVs.
HD viewing also differs by age, ethnicity and areas of interest. See Nielsen's official blog for more.
