The story
The Old Colony Memorial, which claims the title of oldest weekly newspaper in New England, was founded in 1822 in Plymouth, Massachusetts. The Memorial had become the flagship of a nine-paper chain stretching from Plymouth north to the Boston suburbs by the turn of the 21st century.
Dailies
K. Prescott Low, whose family had published The Patriot Ledger for a century, purchased MPG in 1979 and incorporated it into the privately owned George W. Prescott Publishing Company. Thirty years later, however, in 1997, Low found that "mega-players competing with us" made family ownership of the Ledger and MPG uneconomic, and sought to sell them.
A buyer quickly emerged: James F. Plugh, owner of The Enterprise, the Brockton daily newspaper that competed with the Ledger and several MPG papers. Plugh's Newspaper Media LLC, later renamed Enterprise NewsMedia, bought the Prescott Publishing for an estimated US$60 to US$70 million.
Toward the end of Plugh's ownership of MPG, the company began expanding. In 2005, MPG purchased the Call Group of three weeklies in the Taunton area, as well as the Norwood Bulletin. A year later, Plugh purchased Associated and Independent Newspapers, an independent chain of 12 weeklies in the suburbs around Brockton.
GateHouse
Liberty Publishing purchased Enterprise NewsMedia in 2006 as part of a mammoth deal that also included Community Newspaper Company—then owned by the Boston Herald—and a new name for the parent company, GateHouse Media.
Under GateHouse, MPG was gradually folded into CNC's South Unit. In a reorganization announced October 1, 2006, MPG's executives were reassigned to CNC positions and a handful of newspapers were closed to eliminate competition within the merged company. Additionally, MPG papers that had been printed in tabloid format became broadsheets and would now be printed at CNC presses.
