PITTSFIELD, Mass. (AP) — As many local news outlets struggle to survive, the owners of a small New England newspaper chain are trying to show that investing in the newsroom will translate into paying readers. Its flagship daily in the Berkshires of western Massachusetts has hired more reporters, added sections, begun hosting community events and even improved the quality of the paper on which it’s printed. Even so, the newspaper is still fighting to attract subscribers. If it fails, it won’t be for lack of effort.
