U.S. Senate Judiciary Committee Chairman Patrick Leahy on Thursday pressed large Internet providers to pledge that they will not strike deals that may help some websites load faster than others or give similar "fast lanes" to affiliated services. As regulators work on new so-called "net neutrality" rules, Leahy wrote to chiefs of AT&T Inc, Verizon Communications Inc, Time Warner Cable Inc and Charter Communications Inc. In his letters, similar to one sent to Comcast Corp on Monday, Leahy asked the leading Internet service providers to formally commit to no so-called "paid prioritization" deals in which content companies could pay Internet providers to ensure smooth and fast delivery of their traffic.
