The Tribune Company will expand its local entertainment guide Metromix throughout its newspaper chain. The Metromix site will be up and running in New York City this week, and it has already been introduced at the Los Angeles Times, the company has announced.

The guide began in Chicago ten years ago, where it is linked with the Chicago Tribune and free daily Red Eye.

Baltimore and Orlando already have their own versions (it's called CityBeat, powered by metromix.com, in Orlando), and the company says it will launch Metromix in each of its newspaper markets.

Metromix is targeted at “young and socially active” people, and contains information on restaurants, bars, clubs, movies, concerts and all other entertainment information young adults would be interested in. It also provides a target audience for advertisers.
