Ms. Buckingham recalled conducting a focus group where one of her subjects, a college student, said, “If the news is that important, it will find me.”
A December survey by the Pew Research Center for the People and the Press looked broadly at how media were being consumed this campaign. In the most striking finding, half of respondents over the age of 50 and 39 percent of 30- to 49-year-olds reported watching local television news regularly for campaign news, while only 25 percent of people under 30 said they did.
Fully two-thirds of Web users under 30 say they use social networking sites, while fewer than 20 percent of older users do. MySpace and Facebook create a sense of connection to the candidates. Between the two sites, Mr. Obama has about one million “friends,” Senator Hillary Rodham Clinton, his rival for the Democratic nomination, has roughly 330,000, and Senator John McCain, the presumed Republican nominee, has more than 140,000. Four out of 10 young people have watched candidate speeches, interviews, commercials or debates online, according to Pew, substantially more than people 30 and older.
Young people also identify online discussions with friends and videos as important sources of election information. The habits suggest that younger readers find themselves going straight to the source, bypassing the context and analysis that seasoned journalists provide.
In the days after Mr. Obama’s speech on race last week, for example, links to the transcript and the video were the most popular items posted on Facebook. On The New York Times’s Web site, the transcript of the speech ranked consistently higher on the most e-mailed list than the articles written about the speech.
