Accounting Policies [Abstract]
Description of Business	Description of Business. RealNetworks provides digital media software and services to consumers, mobile carriers, device manufacturers, system integrators, and other businesses. Consumers use our digital media products and services to store, organize, play, manage and enjoy their digital media content, either directly from us or through our distribution partners. We have recently developed a new generation of artificial intelligence (AI)-based products and solutions. The main two products and key investment initiatives in our AI portfolio are SAFR, our AI-based computer vision platform, and KONTXT, our natural language processing-based message classification and analysis platform. Inherent in our business are various risks and uncertainties, including a limited history of certain of our product and service offerings. RealNetworks' success will depend on the acceptance of our technology, products and services and the ability to generate related revenue and cash flow. In this Quarterly Report on Form 10-Q (10-Q or Report), RealNetworks, Inc., together with its subsidiaries, is referred to as "RealNetworks," the "Company," "we," "us," or "our." "RealPlayer," "RMHD," "RealMedia," "GameHouse," "KONTXT," "SAFR" and other trademarks of ours appearing in this report are our property.
Basis of Presentation	Basis of Presentation. The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries in which it has a more than 50% voting interest. Noncontrolling interests represent third-party ownership in the equity of Scener Inc. ("Scener"), which was deconsolidated on June 30, 2021, and are reflected separately in the Company's financial statements. See Note 12. Related Party Transactions for additional details. Intercompany balances and transactions have been eliminated in consolidation. The unaudited condensed consolidated financial statements reflect all adjustments, consisting only of normal, recurring adjustments that, in the opinion of management, are necessary for a fair presentation of the results of operations for the periods presented. Operating results for the quarter and six months ended June 30, 2022 are not necessarily indicative of the results that may be expected for any subsequent period or for the year ending December 31, 2022. Certain information and disclosures normally included in financial statements prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (SEC).
Liquidity and Capital Resources Text Block	Liquidity and Capital Resources. The Company continues to incur operating losses, including net operating losses of $4.9 million and $9.9 million for the three and six months ended June 30, 2022, respectively. The Company had an accumulated deficit of $581.2 million and $570.8 million as of June 30, 2022 and December 31, 2021, respectively. Our unrestricted cash and cash equivalents balance was $14.4 million as of June 30, 2022. We have evaluated our current liquidity position in light of our history of declining revenue and operating losses as well as our near-term expectations of net negative cash flows from operating activities. Moreover, our operating forecast is partly dependent on factors that are outside of our control, including the ongoing effects of the coronavirus pandemic and related impacts on global commerce and financial markets. These conditions raise substantial doubt about our ability to continue as a going concern within 12 months from the date of this filing. Our financial statements do not include any adjustment relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should we be unable to continue as a going concern. We intend to use our existing unrestricted cash balances to fund our short-term working capital needs. We have active plans to mitigate these conditions. Specifically, we plan to reduce negative cash flow through operating expense reductions. In addition, we are evaluating various strategic opportunities, which may include selling certain businesses or product lines, soliciting external investment into certain of our businesses, or seeking other strategic partnerships. Our plans are subject to inherent risks and uncertainties. Accordingly, there can be no assurance that our plans can be effectively implemented and, therefore, that the conditions can be effectively mitigated.
Risk and Uncertainties Text block	Risks and Uncertainties. In March 2020, the World Health Organization declared the outbreak of the coronavirus that causes COVID-19 to be a global pandemic. As the virus spread throughout the U.S. and the world, authorities implemented numerous measures to contain the virus, including travel bans and restrictions, quarantines, shelter-in-place orders, business limitations, and shutdowns. In addition to the pandemic's widespread impact on public health and global society, reactions to the pandemic as well as measures taken to contain the virus have caused significant turmoil to the global economy and financial markets. Moreover, similar to other companies, we have taken steps to support the health and well-being of our employees, customers, partners and communities, which include working remotely and learning to operate our businesses in a fundamentally different way. The COVID-19 pandemic, including the emergence of variants such as the delta and omicron variants, and the resultant economic instability and financial market turmoil has added complexity, uncertainty and risk to nearly all aspects of our business. It is difficult to predict the near-term and long-term impacts that the pandemic will have on our results from operations, financial condition, liquidity and cash flows. In the preparation of our financial statements, certain estimates and assumptions regarding these impacts have been made, which could change in future periods and which could differ from actual outcomes.
Use of Estimates	Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
