AT&T is ready to lease access to its cables to rivals who want to provide their customers with high-speed internet access. That’s according to The Washington Post. The paper quotes sources who say AT&T will first announce a deal with MindSpring Enterprises today. AT&T has been criticized by consumer groups and municipalities since it bought more than half the nation’s cable lines. The Post quotes sources who say the communications giant will formally agree to eventually allow rival firms to access its cables for the right price.
