Addressing WIA's claim that NAB has engaged in a "misinformation campaign" and that the testing process "should be left to the FCC's expert engineers," NAB Executive Vice President Dennis Wharton responded:

"A successful consumer transition from analog to digital television is now imperiled by a cadre of companies that have been hoisted on their own flawed technology petard. Try as they might, portable unlicensed device advocates like Google and Microsoft cannot run and hide from the fact that their own technology utterly failed FCC testing. That is not 'misinformation,' but rather an inconvenient truth.
