We have a variety of service-related types, and it makes not sense for BroadcastService to sit at the top below http://schema.org/Thing - let's find a better home for it. Proposal: set supertype of BroadcastService to be http://schema.org/Service. It was a mistake to add it under Thing, rather than under Intangible or Service.

Nearby we currently have:

• http://schema.org/Service http://www.w3.org/2000/01/rdf-schema#subClassOf http://schema.org/Intangible .
• http://schema.org/FinancialService http://www.w3.org/2000/01/rdf-schema#subClassOf http://schema.org/LocalBusiness .
• http://schema.org/ProfessionalService http://www.w3.org/2000/01/rdf-schema#subClassOf http://schema.org/LocalBusiness .

Although you could argue that the FinancialService and ProfessionalService types aren't necessarily local and also shouldn't be all under http://schema.org/Service, that's a wider debate.

http://schema.org/Service seems a bearable if vague fit. It is under Intangible, and already has a couple of subtypes (Taxi and GovernmentService).
