The group, the Don't Count Us Out Coalition, planned a protest in Los Angeles yesterday.
Nielsen, a unit of VNU, said in a statement
Nielsen also confirmed plans to launch people meters in Chicago on Aug. 5 and San Francisco on Sept. 30. In New York, where people meters are already in use, paper diaries will be discontinued Aug. 25.
The Media Ratings Council, an audience-measurement audit body, is reviewing the latest Nielsen people meter in Los Angeles for accuracy and is yet to accredit Nielsen's New York system.
The Don't Count Us Out Coalition contends that the new local people meters are not adequately representing minority audiences.
