In June 2000, Tribune acquired the Los Angeles–based Times Mirror Company in a US$8.3 billion merger transaction, the largest acquisition in the history of the newspaper industry, effectively doubling the size of Tribune's newspaper holdings. The Times Mirror merger added seven daily newspapers to Tribune's existing publishing properties, including the "Los Angeles Times", the Long Island-based "Newsday", "The Baltimore Sun" and the "Hartford Courant". Through the deal, Tribune became the only media company that owned both newspapers and television stations in the three largest media markets of New York City, Los Angeles and Chicago, as a result of cross-ownership waivers that were approved by the FCC.
