In June 2004, the last time the Pew Internet Project asked about listening to music online, Millennials were by far the most avid listeners: 55% of Millennials had streamed music online, compared to 36% of Gen Xers and 34% of all adults. As of September 2009, Millennials still lead in this activity—65% have done so—but their lead is more modest, with Gen X and Younger Boomers not too far behind. The oldest generations, however, have seen the least growth. One in four members of the Silent Generation streaming music, and the G.I. Generation still listens at roughly the same rate: 12% in September 2009 versus 14% in June 2004.
