CY2021	us-gaap	Use Of Estimates UseOfEstimates	The preparation of Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying Notes. Such estimates include, but are not limited to, valuation of business combinations including acquired intangible assets and goodwill, loss contingencies, the recognition and measurement of current and deferred income taxes, including the measurement of uncertain tax positions, and valuation of assets and liabilities and results of operations of our discontinued operations. On an ongoing basis, management determines these estimates and assumptions based on historical experience and on various other assumptions that are believed to be reasonable. Third-party valuation specialists are also utilized for certain estimates. Actual results could differ from such estimates and assumptions due to risks and uncertainties, including uncertainty in the current economic environment due to the COVID-19 pandemic, and such differences may be material to the Consolidated Financial Statements.

CY2021	us-gaap	Concentration Risk Credit Risk ConcentrationRiskCreditRisk	A significant portion of our revenue is derived from international sales. Fluctuations of the U.S. dollar against foreign currencies, changes in local regulatory or economic conditions, or piracy could adversely affect our operating results.Financial instruments that potentially subject us to concentrations of risk consist principally of cash and cash equivalents, short-term investments, and trade accounts receivable. Our investment policy limits the amount of credit risk exposure to any one issuer and to any one country. A majority of our trade receivables are derived from sales to distributors and retailers. The credit risk in our trade accounts receivable is substantially mitigated by our credit evaluation process, reasonably short collection terms, and the geographical dispersion of sales transactions.
