Brian Carthy works as a Gaelic Games Correspondent and Commentator for RTÉ, specialising in Gaelic games. In possession of a nationwide profile, Carthy has also written a number of books with a sporting theme. Carthy is a native of Ballymore, near Strokestown, County Roscommon.
In 2011, Carthy was "downgraded" by RTÉ. This prompted a response from numerous Gaelic games figures, including Mickey Harte, Kieran McGeeney and Justin McNulty, who felt this mistreatment of Carthy was unfair. Those who disagreed with RTÉ's treatment of Carthy wrote a four-page letter to director general Noel Curran and boycotted the organisation.
In 2012, his son John Brian won an All-Ireland U-21 Football Championship medal playing in goal for Dublin against Brian's native Roscommon and was part of the U-21 squad again in 2013.
