Over the last two decades, as the number of media choices available to consumers has exploded, so too have worries over self-selection into media audiences. Some fear greater apathy, others heightened polarization. In this article, we shed light on the latter possibility.

We identify the impact of access to broadband Internet on affective polarization by exploiting differences in broadband availability brought about by variation in state right-of-way regulations (ROW).

We merge state-level regulation data with county-level broadband penetration data and a large-N sample of survey data from 2004 to 2008 and find that access to broadband Internet increases partisan hostility. The effect occurs in both years and is stable across levels of political interest.

We also find that access to broadband Internet boosts partisans' consumption of partisan media, a likely cause of increased polarization.
