Longtime media biz reporter Ron Grover has exited his post as Los Angeles bureau chief of Reuters after three years with the global news service.

Grover’s departure comes amid a flurry of transitions for established players on media beat, including Bill Carter’s pending exit from the New York Times after 25 years as its top TV reporter.

Reuters has recently undergone management restructuring and some belt-tightening in its editorial operations. Los Angeles Times alum Sue Horton was named a top news editor for Reuters based on the West Coast earlier this month.

A respected business writer, Grover came to Reuters in 2012 after more than 30 years with BusinessWeek and its successor, Bloomberg BusinessWeek. He’s been a Los Angeles-based scribe covering media and entertainment since 1986. In 1991 Grover authored “The Disney Touch,” a study of the turnaround at the Magic Kingdom under Michael Eisner and Frank Wells.

Reuters and Grover declined comment. It’s understood that Grover aims to continue writing about media and entertainment, in addition to doing some consulting work and pursuing a book project.

Reuters set a news syndication partnership with Variety in June.
