Number of TV Homes Shrinks for Second Consecutive Year Bloomberg

The number of U.S. television households has fallen for a second consecutive year, reflecting the emergence of online viewing, reports Bloomberg.

The estimated number of TV homes dropped by 500,000 to 114.2 million, according to Nielsen, with the change being reflected for ratings purposes starting this week with the launch of the 2012-13 TV season, the story notes.

Nielsen previously reduced the number of TV homes in May 2011 by 1%, marking the first decline since 1990, according to the article.

The ratings firm said it's working with advertising and television clients to decide how to define a TV home and how to account for new devices such as tablet computers, the piece adds.
