Roberts ).〕 Much of Roberts' research concerns the effects of media on youth.〔.〕 A notable study coauthored by Roberts and Ulla Foehr for the Kaiser Family Foundation found that, at the turn of the millennium, U.S. children spent the equivalent amount of time to a full-time job watching television and other media,〔.〕〔.〕〔.〕 and a later follow-on study by Roberts and others coined the name “Generation M” for the youth of the day after discovering that they were packing even more media into their schedules by multitasking.〔.〕〔(Generation M: Media in the Lives of 8-18 Year-olds ), Kaiser Family Foundation, 2005.〕 Roberts also studied depictions of drug use and violence in media,〔.〕〔.〕 and took part in 1997 U.S. Senate hearings on violent music lyrics.〔.〕 Roberts' research provided the foundation for the content rating systems of the Recreational Software Advisory Council, of which he was a board member,〔(Recreational Software Advisory Council Launches Objective, Content-Labeling Advisory System for the Internet ). RSAC, February 28, 1996.〕〔.〕 and its successor organization the Internet Content Rating Association.〔(Internet Content Rating Association Formed to Provide Global System for Protecting Children and Free Speech on the Internet: AOL, IBM, Microsoft and Recreational Software Advisory Council Join Forces with Other Global Organizations to Create and Manage International Online Rating System ).
