Why use articles?
Companies are often covered to a greater extent in their "hometowns" or in cities where they have extensive operations. Local newspapers may cover financial news, expansions (i.e. a new headquarters or the opening of a new manufacturing facility), charitable activities, and even corporate officers in greater detail than might be found in more general national newspapers and magazines.
When conducting company research, in order to have the most complete view of a company, including who they are "where they live," be sure to perform several searches in local publications.
