FCC Chairman Tom Wheeler used his talk at CES today to put AT&T’s controversial new “Sponsored Data” program on notice. “My attitude is: let’s take a look at what this is, let’s take a look at how it operates,” Wheeler said. “And be sure, that if it interferes with the operation of the internet; that if it develops into an anticompetitive practice; that if it does have some kind of preferential treatment given somewhere, then that is cause for us to intervene.”
