Parallax World vs TennisKeeper

Parallax World is an international affairs journal that covers the news through three different perspectives.

News readers are increasingly insulating themselves with news and social media that supports their existing bias. The primary goal of Parallax World is to tackle this issue of partisanship in the United States by giving readers three leading perspectives on international events, so readers can decide for themselves what perspectives they agree with. New original content is published every business day.
