Berlin's main industry in the early 20th century was the pulp and paper industries, which have been in a long decline since that time. As jobs left the area, the population has decreased and is about half its peak of more than 20,000 in the 1930 census. In 1917, the Berlin Mills Company was renamed the Brown Company, because of World War I and anti-German feeling against the enemy of the time. A short time after the Great Depression, the Brown Company went into receivership. Surviving with governmental help, it was bought and sold several times after World War II.
