Broadcast television Pros: + It's local. You get local news, weather and information. + They are more responsive to viewers. + It's free. all one needs to do is put up an antenna. + It's better quality. Cable and satellite systems must compress signals to make room for more channels. Compression reduces resolution. + It's federally regulated. The FCC puts limits on what can be shown. Cons: - It's federally regulated. The FCC puts limits on what can be shown. - Fewer channels. Cable/Satellite: Pros: + It's not as highly regulated. Almost anything can be shown. + More channels. + Offer additional services such as Broadband Internet and phone. + Can offer On Demand and "replay" services. Cons: - It's not as highly regulated. Almost anything can be shown. - Less local. "Must carry" laws had to be implemented to make sure that local communities were served before profits. Some communities require "community access" channels in their franchise agreements to make sure the Cable Company pays at least some attention to community needs.. - Costs. A monthly fee must be paid for service. Pricing structures constantly change. - Less responsive to customers. - Quality generally is lower due to compression to add more channels. - Generally no competition: In most areas, one cable company servers all subscribers. Satellite and Telco offerings are changing this, though. I may edit and add to the list as I think of more . . .
