There was dramatic growth in the cable industry once the act went into effect. However, it remained largely in the hands of few local monopolies that were able to determine the content of the programs and set the rates for services and channels on their system. These changes in authority were not immediate, but evolved over the course of a few years. Cable consumers were outraged with the increases in prices and services, whereas municipalities were annoyed with violated contracts. Many of these outcomes can be attributed to the Federal Communication Commission's (FCC) interpretation of Congress' mandates, which contained poor choice of language and confusion over the First Amendment to the United States Constitution.
