| Adjustment to Non-PEO NEO Compensation Footnote [Text Block] | In calculating CAP, the following assumptions were made with respect to adjustments: (a) for PRSUs and RSUs awarded to the CEO and non-CEO NEOs, which included grants made from 2017 through 2022, the awards were re-valued based on the applicable WBD or DISCA stock price on each of December 30, 2020 ($30.09), December 31, 2021 ($23.54) and December 31, 2022 ($9.48); and (b) for stock options awarded to the CEO and non-CEO NEOs, which included grants made from 2016 through 2022, the awards were re-valued as of December 31, 2020, December 31, 2021 and December 31, 2022 using the Black-Scholes option-pricing model. The assumptions used for each valuation date included stock price, risk-free rate, stock price volatility and expected life as determined in accordance with FASB ASC Topic 718.

| Additional 402(v) Disclosure [Text Block] | Net Income is as reported in our Annual Report on Form 10-K for the applicable year. The following graphs illustrate the relationship between the CAP of our CEO and average non-CEO NEO ("Average NEO") and WBD's TSR, Net Income and Adjusted EBITDA performance over the three-year period from 2020 to 2022. While not graphically presented, our three-year TSR performance versus that of our selected peer group, the S&P 500 Media and Entertainment Index, overall followed a similar trajectory. The volatility in our stock price over the three-year period can be attributed to the impact of the WarnerMedia Transaction, as well as other separate factors that were beyond our control. While the Committee believes that driving stock price appreciation and TSR performance are important objectives for our CEO and non-CEO NEOs, it also believes that achieving other financial objectives, such as Adjusted EBITDA and Adjusted Free Cash Flow, as well as achieving other strategic objectives, such as growing our DTC business and closing and integrating the WarnerMedia Transaction, are equally important and it has sought to align our executive compensation with these objectives, as further discussed in the CD&A in this proxy statement. The three-year compensation history of the CEO and the average NEO shows that the disclosed CAP generally aligns with WBD's TSR, Net Income and Adjusted EBITDA performance. The exception to this was the CEO's CAP in 2021 which includes the option grant made to Mr. Zaslav in connection with the signing of the WarnerMedia Transaction and his entry into a new employment agreement. All of the 2021 options awarded to Mr. Zaslav have a strike price that is higher than the current trading price of WBD common stock. If the 2021 option grant were excluded, Mr. Zaslav's CAP in 2021 would have been substantially lower and better aligned with TSR, Net Income, and Adjusted EBITDA performance for the three-year period. Under Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are required to provide the ratio of the annual total compensation of our CEO to the annual total compensation of the median-paid employee of the Company (“Median Employee”). Our 2022 CEO to Median Employee pay ratio was calculated in accordance with Item 402(u) of Regulation S-K, and represents a reasonable estimate. For 2022, we re-identified our Median Employee and adjusted our methodology due to the change in our employee population as a result of our completion of the WarnerMedia Transaction on April 8, 2022. To determine our employee population, we defined “employee” as any full-time, part-time or temporary individual employed and paid by us or any of our consolidated subsidiaries as of December 31, 2022. We did not include freelance workers, temporary individuals employed and paid by a third party or independent contractors. To identify the Median Employee from our employee population, we used base salary amounts as of December 31, 2022 as our consistently applied compensation measure. For employees paid in foreign currencies, we converted their base salary into U.S. dollar amounts using an exchange rate as of December 31, 2022. We then sorted the employees (excluding our CEO) by their U.S. dollar equivalent base salary amounts and thereby identified our Median Employee. Using the same methodology we used for our NEOs (including our CEO) as set forth in the 2022 Summary Compensation Table resulted in our Median Employee having annual total compensation of $172,735. The 2022 annual total compensation for our CEO as disclosed in the 2022 Summary Compensation Table was $39,288,458. Therefore, the ratio of our CEO’s annual total compensation to the Median Employee’s annual total compensation was 227 to 1. | | |
