The net neutrality rules passed by the Federal Communications Commission back in February permit it to examine cable and broadband pricing to ensure customers are treated fairly. Four Senators are urging Tom Wheeler and the FCC to do just that. The group, led by Senator (and Democratic presidential candidate) Bernie Sanders (I-VT), cites the limited options as a cause for price increases, asking for the FCC's help in "empowering Americans with more information." The effort looks to offer customers the details about rates and how their monthly bills are calculated by their service provider. In a letter sent by the group this week, the Senators use the example of Time Warner Cable increasing modem rental fees by 203 percent over a three-year period -- a change that customers may not have been aware of when their monthly bill went up.
