The United States media industry is dominated by large vertically integrated corporations. It has a population of 320 million people and is projected to be worth $337.1 billion by 2018, a 8.2% increase over five years. However, press freedom has declined as the government has charged more journalists under the Espionage Act than ever before. The largest players are Comcast, which may merge with Time Warner to become the biggest media company globally, and other corporations like CBS and Disney that own broadcasting networks, cable channels, and movie studios.
