Pew research two weeks out from the election:
The biggest gains have come on the internet-both to the websites of traditional news sources and those native to the web.
Social media platforms such as Facebook, Twitter and YouTube are growing especially rapidly as a source of political news. The number of Americans who say they regularly go to these destinations to learn about the campaign has doubled since January. Even with that jump, however, these leading social media platforms are still turned to by a relatively limited number of Americans, about 17% in all, when those who mentioned at least one of those platforms are combined.
[...] The numbers portray a diverse landscape in which no platform dominates as the place for politics, and the vast majority of Americans say they regularly rely on multiple platforms to get political information. Just 6% said they turn regularly to just one platform.
Cable news channels continue to have the furthest reach, but a number of other destinations are close. Currently, 41% of Americans say they regularly learn about the candidates or the campaign from cable news networks, up five percentage points from 36% during the primaries.
But local TV news is almost as popular as a means for learning about the campaign; 38% of Americans regularly use it to learn about the candidates and the election, up six points since the primaries.
That is now nearly matched by the internet, which has seen an increase of 11 points in the number of Americans who say they regularly turn to it for campaign news since the year began. Fully 36% of Americans say they regularly get election news there, up from 25% in January.
For comparison purposes, a 2008 Pew survey showed the Internet was gaining fastest among younger demographics — a trend which continued even more rapidly through 2012.
