From our colleagues at the Pew Research Center for the People & the Press:
Many more Americans are turning to the internet for campaign news this year as the web becomes a key source of election news. Television remains the dominant source, but the percent who say they get most of their campaign news from the internet has tripled since October 2004 (from 10% then to 33% now).
While use of the web has seen considerable growth, the percentage of Americans relying on TV and newspapers for campaign news has remained relatively flat since 2004. The internet now rivals newspapers as a main source for campaign news. And with so much interest in the election next week, the public’s use of the internet as a campaign news source is up even since the primaries earlier this year. In March, 26% cited the internet as a main source for election news, while the percentages citing television and newspapers remain largely unchanged.
