The Boston Globe is, based on several accounts, losing $1 million a week. One investment bank recently said the paper is worth only $20 million. The paper is the flagship of what the Globe’s parent, the New York Times, calls the New England Media Group. The Times has substantial financial problems of its own. Last year, ad revenue for the New England properties was down 18%. That is likely to continue or get worse this year. Supporting larger losses at the Globe will become nearly impossible. Boston.com, the online site that includes the digital aspects of the Globe, will probably be all that remains of the operation.
