| Adjustment To PEO Compensation, Footnote [Text Block] | In accordance with the SEC rules, the “Actual Pay” reflected in this column is computed by (i) subtracting the amounts in the “Stock Awards” column of the SCT for each year from the “Total” column of the SCT and then, (ii) adding the fair value as of the end of the fiscal year of awards granted during the year that are outstanding and unvested as of the end of the year, (iii) adding the change in fair value from the last day of the prior year to the last day of the reported year of equity awards that are outstanding and unvested, (iv) adding the change in fair value of awards (or portion thereof) that vested in the reported year as of the vesting date, compared to the fair value from the last day of the prior year, (v) adding the value of accrued dividends paid in the reporting year, (vi) subtracting the fair value as of the last day of the prior year of equity awards that forfeited during the reported year. Fair values of awards are computed in a manner consistent with the fair value methodology used to account for share-based payments in the Company’s financial statements completed according to the U.S. generally accepted accounting principle (“GAAP”).

| Measure Name | Adjusted OIBDA | | |
| Non-GAAP Measure Description [Text Block] | The SEC rules require us to designate a “company-selected measure” that in our assessment represents the most important financial performance measure (that is not TSR or net income) used by the Company to link the “Actual Pay” of our NEOs for the most recently completed fiscal year to our performance. We selected Adjusted OIBDA as this measure for 2022. Adjusted OIBDA is a non-GAAP measure. For reconciliations of operating income to Adjusted OIBDA referenced throughout this section, see the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Performance Indicators—Reconciliation of Non-GAAP Financial Measures,” on pages 44-45 of our Annual Report on Form 10-K for the year ended December 31, 2022. This performance measure may not have been the most important financial performance measure for years 2021 and 2020 and we may determine a different financial performance measure to be the most important financial performance measure in future years. | | |
