(Reuters) - Tribune Media Co <TRCO.N>, one of the largest U.S. TV station operators, said on Wednesday Chief Executive Peter Liguori would step down in March.


Liguori joined Tribune in 2013 and led the spin-off of its newspaper business into a separate company now known as Tronc Inc <TRNC.O>.


"It became clear to Peter and the board that in this last year of his contract it was time to find a new CEO to run the more broadcast-centric company," Bruce Karsh, chairman of Tribune's board said.


In December, Liguori also led the sale of Tribune media data unit, Gracenote, to advertising tracking company Nielsen Holdings Plc <NLSN.N> for $560 million.


Tribune's board named director Peter Kern as interim CEO during the search process.
