Project Purpose

For-profit television news is funded in part through advertising. To boost viewership, commercial news channels set aside journalistic standards in favor of sensational and emotional styles of programming. Furthermore, partisan channels, such as conservative media, selectively report or distort information for political gain. These deviations from journalistic standards have real world consequences that effect lives and families of even non-viewers. Therefore everyone has a right to know whose dollars are funding these channels.

Sampling Strategy

The most comprehensive way to know who is advertising on a particular channel would entail watching every hour every day, yet this is not feasible for volunteers. Therefore the notion of “sampling” is used to gather data with less effort. Our strategy is that nearly every day a volunteer watches a channel for a fifteen minute interval at an arbitrary time (excluding overnight), and collects data about observed advertisements. Over time this should generate a comprehensive picture of advertising on a particular channel.

Data Collection

The following data is collected for each observed advertisement:

CompanyName, ProductName, DateObserved, TimeOfDay, Channel, ShowName

Data Files

Currently data is only being collected about Fox News Channel, and the following files are available in the repository:


WhoAdvertisesOn is not just a project tracking and summarizing advertising on a single partisan news outlet. It is also an open source data science toolkit that can allow any person or organization to do the same for their own purposes and in their own contexts. Doing so does not require advanced coding skills. Read the Toolkit Guide here.
