I can not Join NAB or my local State Association, as both do not recognize me as being part of the broadcasting industry.
The NAB defines themselves as radio & TV broadcasters. Private groups are allowed to define themselves how they want, and restrict membership to whoever they want. SiriusXM isn't a member either. Neither is Spotify. Why would you want to join the NAB? What would they do for you?
Back to my question: What broadcasting laws are you required to follow?
