"We do not sell our broadband customers' individual web browsing history. We did not do it before the FCC's rules were adopted, and we have no plans to do so," Comcast's chief privacy officer Gerard Lewis said.
Verizon does not sell personal web browsing histories and has no plans to do so in the future, said spokesman Richard Young.
AT&T "will not sell your personal information to anyone, for any purpose. Period," AT&T said in a statement.
