Revenue Recognition [Abstract]
Revenue Recognition	(5) Revenue Recognition: We categorize our products, services, and other revenues into the following categories: Data and Internet services include broadband services for consumer and business customers. We provide data transmission services to high volume business customers and other carriers with dedicated high capacity circuits (“nonswitched access”) including services to wireless providers (“wireless backhaul”); Voice services include traditional local and long-distance wireline services, Voice over Internet Protocol (VoIP) services, as well as a number of unified messaging services offered to our consumer and business customers. Voice services also include the long-distance voice origination and termination services that we provide to our business customers and other carriers; Video services include revenues generated from services provided directly to consumer customers as linear terrestrial television services, through Dish satellite TV services, and through partnerships with over-the-top (OTT) video providers. Video services also includes pay-per-view revenues, video on demand, equipment rentals, and video advertising. The Company has made the strategic decision to limit sales of new traditional TV services focusing on our broadband products and OTT video options; Other customer revenue includes switched access revenue, rents collected for collocation services, and revenue from other services and fees. Switched access revenue includes revenues derived from allowing other carriers to use our network to originate and/or terminate their local and long-distance voice traffic (switched access). These services are primarily billed on a minutes-of-use basis applying tariffed rates filed with the FCC or state agencies; and Subsidy and other regulatory revenue includes revenues generated from cost subsidies from state and federal authorities, including the Connect America Fund Phase II.
