As the U.S. midterm elections approach next week, there is a renewed focus on understanding the spending on and claims made in political advertising in digital channels, particularly on social media. But what is going on across the web, beyond the social media platforms?

A recent report from the University of North Carolina at Chapel Hill Center on Technology Policy found that as a result of restrictions on political ads instituted by major platforms ahead of the 2020 elections, political advertisers are increasingly turning to political advertising on other platforms. Programmatic advertising accounts for a substantial and increasing share of political advertising, they say, and more attention needs to be paid to this complex and confusing ecosystem of companies- large and small- that serve up ads on websites, apps, streaming services, and other digitally connected devices. This episode features a discussion with the report's authors, J. Scott Babwah Brennen & Matt Perault.
