In recent years, efforts to find a sustainable business model for local news coverage in the U.S. have resulted in the acquisition of local news organizations in different markets by large, national companies. Last week's announcement of a merger between Gannett and Gatehouse media, which would consolidate ownership of more than 260 local newspapers, is the latest in a trend that also affects local TV, with companies such as Sinclair Broadcast Group buying stations around the country.
