"A series of tubes" is a phrase coined originally as an analogy by then-United States Senator Ted Stevens (R-Alaska) to describe the Internet in the context of opposing network neutrality. On June 28, 2006, he used this metaphor to criticize a proposed amendment to a committee bill. The amendment would have prohibited Internet Access providers such as AT&T, Comcast, Time Warner Cable, and Verizon Communications from charging fees to give some companies' data a higher priority in relation to other traffic. The metaphor has been widely ridiculed, particularly because Stevens displayed an extremely limited understanding of the Internet, even though he was in charge of regulating it. Edward Felten, Princeton University professor of computer science, pointed out the unfairness of some criticisms of Stevens' wording, while maintaining that the underlying arguments were rather weak.
