A.T. & T. had to abide by a "common carriage" rule: it provided the same quality of service to all, and could not favor one customer over another. But, while "tiered access" never influenced the spread of the telephone network, it is becoming a major issue in the evolution of the Internet. Until recently, companies that provided Internet access followed a de-facto commoncarriage rule, usually called "network neutrality," which meant that all Web sites got equal treatment. Network neutrality was considered so fundamental to the success of the Net that Michael Powell, when he was chairman of the F.C.C., described it as one of the basic rules of "Internet freedom."
