Writing in "Communication Law and Policy", David Pritchard, Christopher Terry and Paul R Brewer did not agree with the ruling, or the premises behind the Citizen Activist groups. In a series of studies, they found that the proprietors of the cross-ownerships in their study permitted their media outlets to publish and broadcast a diversity of viewpoints. What is more, the slant of news and opinion in non-cross-owned media was not significantly different from that of cross-owned media. At least in the context of newspaper-broadcast cross-ownership, such findings undermine the premise that each media owner constitutes a single voice on important subjects such as presidential elections.
