* National Cable & Telecommunications Association (NCTA) (from 1976 to 1984, becoming president in 1979)[1]
* Cellular Telecommunications & Internet Association (CTIA) (from 1992 to 2004, serving as CEO)[1]
It's pretty disingenuous to note his lobbying for cable companies in the 1970's and 1980's, before they even entered the Internet service business, while ignoring that his most recent connections are to Internet companies that ride on the infrastructure built by the telecoms.
Also, CTIA represents wireless carriers, which are under a different regulatory umbrella than telcos or cable. To the extent you can infer bias from Wheeler's work, the strongest inference is in favor of a bias towards Internet companies, not a bias towards telcos. Of course, I wouldn't characterize him as biased, but rather as someone with experience with the "full stack."
