HD Sets in Over Three-Quarters of U.S. Homes: NielsenBut Still Only 25% of Primetime Cable Viewing Occurs in 'True' HD 10/17/2012 10:18 AM Eastern
In May 2012, 61% of all primetime viewing was done on an HD set, but much of that viewing was of standard- definition feeds, according to Nielsen. During that month about 29% of English-language broadcast primetime viewing and 25% of cable primetime viewing was in "true HD," the study found.
For "true HD" viewing to occur, the HD set must be connected to an HD signal and the set needs to be tuned to a HD channels.
As expected sports and entertainment genres are more likely to be viewed in HD than news and kids programming.
The Nielsen study was based on usage of 17 networks -- five English-language broadcast networks and 12 ad- supported cable networks -- during May.
