Foer has written for "Slate" and "New York" magazine. He served as editor of American magazine "The New Republic" from 2006 until 2010, when he resigned — by his subsequent account, because of exhaustion over an interminable search for a patron who could save the magazine. He then became editor again in 2012, recruited by new patron Chris Hughes. His book "How Soccer Explains the World" was published in 2004. The book "Jewish Jocks", which he co-edited with "New Republic" writer Marc Tracy, was published in 2012. It won a National Jewish Book Award in 2012. Foer has described it as an effort to avoid the "simple hagiography" he found in some of the many existing books about Jewish sports figures.
