Revenue from Contract with Customer [Abstract]
Revenue Recognition Policy	Residential Services Residential customers are offered Internet, video, voice and mobile services primarily on a subscription basis. Mobile services are sold under unlimited data plans or by-the-gig data usage plans. The Company often provides multiple services to a customer. The transaction price for a bundle of services may be less than the sum of the standalone selling prices of each individual service. The Company allocates the bundle discount among the services to which the discount relates based on the relative standalone selling prices of those services. Generally, directly observable standalone selling prices are used for the revenue allocation. Customers are invoiced for subscription services in advance of the service period. Each subscription service provided is accounted for as a distinct performance obligation and revenue is recognized ratably over the monthly service period as the subscription services are delivered. Residential customers may generally cancel their subscriptions at the end of their monthly service period without penalty. Each optional service purchased is generally accounted for as a distinct performance obligation when purchased and revenue is recognized when the service is provided. For customer premise equipment ("CPE") where such CPE would qualify as a lease, the Company combines the operating lease with the subscription service revenue as a single performance obligation as the subscription service is the predominant component. Installation fees are deferred over the period the fee remains material to the customer, which the Company has estimated to be approximately six months. Sales commission costs are expensed as incurred as the amortization period is less than one year. Right-of-entry costs represent upfront costs incurred related to agreements entered into with multiple dwelling units (“MDUs”) including landlords, real estate companies or owners to gain access to a building in order to market and service customers who reside in the building. Right-of-entry costs are deferred as contract fulfillment costs and recognized over the term of the contracts. Customers can purchase mobile equipment, including devices and accessory products, and have the option to pay for devices under interest-free monthly installment plans. The Company does not impute interest on equipment installment plans sold through its direct channel as the inherent financing component is not considered significant based on the commercial objective of the plans, interest rates prevailing in the marketplace and credit risks of the Company's customers. The sale of equipment is a separate performance obligation, therefore, revenue is recognized from the sale of equipment upon delivery and acceptance by the customer. Fees imposed on the Company by various governmental authorities are passed through on a monthly basis to the Company’s customers and are periodically remitted to authorities. Fees of $1.1 billion for each of the years ended December 31, 2022, 2021 and 2020 are reported in revenues on a gross basis with a corresponding operating expense because the Company is acting as a principal. Certain taxes, such as sales taxes imposed on the Company’s customers, collected and remitted to state and local authorities, are recorded on a net basis because the Company is acting as an agent in such situations. Commercial Services Small and medium business ("SMB") customers are offered Internet, video voice and mobile services similar to those provided to residential customers. SMB customers may generally cancel their subscriptions at the end of their monthly service period without penalty. Each subscription service provided is accounted for as a distinct performance obligation and revenue is recognized ratably over the monthly service period as the subscription services are delivered. Services to enterprise clients include more tailored communications products and managed service solutions to larger businesses, as well as high-capacity last-mile data connectivity services to mobile and wireline carriers on a wholesale basis. Services are primarily offered on a subscription basis with a contractually specified and non-cancelable service period, which is generally one to seven years with a weighted average term of approximately three years. Each subscription service provided is accounted for as a distinct performance obligation and revenue is recognized ratably over the contract period as the subscription services are delivered. Enterprise subscription services are billed as monthly recurring charges to customers and related installation services, if applicable, are billed upon completion of the customer installation. Installation services are not accounted for as distinct performance obligations, but rather a component of the connectivity services, and therefore upfront installation fees are deferred and recognized as revenue over the related contract period. Enterprise sales commission costs are deferred and recognized using a portfolio approach over a weighted-average contract period. Advertising Services The Company offers local, regional and national businesses the opportunity to advertise in individual and multiple service areas on cable television networks and digital outlets. Placement of advertising is accounted for as a distinct performance obligation and revenue is recognized at the point in time when the advertising is distributed. In some service areas, the Company has formed advertising interconnects or entered into representation agreements with other video distributors, under which the Company sells advertising on behalf of those distributors. In other service areas, the Company has entered into representation agreements under which another operator in the area will sell advertising on the Company’s behalf. For representation arrangements in which the Company controls the sale of advertising and acts as the principal to the transaction, the Company recognizes revenue earned from the advertising customer on a gross basis and the amount remitted to the distributor as an operating expense. For other representation arrangements in which the Company does not control the sale of advertising and acts as an agent to the transaction, the Company recognizes revenue net of any fee remitted to the distributor.
