Goodwill and Intangible Assets Disclosure [Abstract]  
Intangible Assets
Our identifiable intangible assets primarily consist of acquired permits and leasehold agreements, and franchise agreements, which grant us the right to operate out-of-home structures in specified locations and the right to provide advertising space on railroad and municipal transit properties. Identifiable intangible assets are amortized on a straight-line basis over their estimated useful life, which is the respective life of the agreement that in some cases includes historical experience of renewals.
