Walt Disney, for example, has approached members of Congress to critically examine whether the proposed merger would exclude rival entertainment companies from reaching Internet consumers. Today's petition marks the entry of major consumer groups into the debate over the deal. The consumer advocacy groups filing today's petition include Consumers Union, the publisher of Consumer Reports magazine; Center for Media Education; Consumer Federation of America; and Media Access Project. "We need a legal obligation to provide nondiscriminatory access to any ISP," said Mark Cooper, research director for the Consumer Federation of America. A Time Warner spokesman said the proposed merger will be good for consumers and offer them more choice. "Our merger will deliver tremendous benefits to consumers, bringing people around the world more choice and more convenience, and accelerating the roll out of broadband services," said a Time Warner spokesman. AOL was not immediately available for comment.
