The network instead has embraced total viewer figures, a move NBC made last year.
"Ever since total viewer ratings were available on a daily basis since 1987, we've tried to move the measurement from households to total viewers," said ABC's Larry Hyams, VP for prime-time audience analysis.
The importance of the adults 18-to-49 demographic among advertisers has been well-documented, with those numbers serving as the best gauge of how a TV*network performs from a sales standpoint.
The debate between households and total viewers is more of a network prestige issue.
CBS plans to stick with household ratings for the time being.
