Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC on March 2, 2020 (the “Annual Report”). The condensed consolidated balance sheet as of December 31, 2019 has been derived from the audited consolidated financial statements as of that date but does not include all of the information and footnotes included in the Company’s Annual Report. The interim financial information is unaudited, but reflects all normal recurring adjustments that are, in the opinion of management, necessary to fairly present the information set forth herein. The results of operations for the three months ended March 31, 2020 are not necessarily indicative of the operating results to be expected for the full year or any future periods. The Company adopted Accounting Standard Codification Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, (“ASC 326”) Credit losses for accounts receivable: The Company maintains an allowance for doubtful accounts to reserve for expected uncollectible accounts receivable. The Company assess collectability by reviewing accounts receivable on a collective basis where similar characteristics exist and on an individual basis when the Company identifies specific customers with known disputes or collectability issues. The Company regularly reviews the allowance by considering historical collectability based on past due status, credit quality, and makes judgments about the creditworthiness of customers based on ongoing credit evaluations. The Company also considers customer-specific information and current economic conditions that may affect a customer’s ability to pay. For the three months ended March 31, 2020, the Company’s assessment of its accounts receivable considered the business and market disruptions caused by the novel coronavirus (“COVID-19”) and emerging credit and collectability trends. The continued volatility in market conditions and evolving shifts in credit trends can be difficult to predict causing volatility that may have a material impact on our allowance for credit losses. See Note 6, for the detailed activity in allowance for doubtful accounts as of March 31, 2020 and December 31, 2019. Use of Estimates The preparation of the Company’s consolidated financial statements in accordance with U.S. GAAP requires management to make certain estimates, judgements, and assumptions that affect the reported amounts of assets, liabilities, net revenue and expenses. Significant items subject to such estimates and assumptions include: for revenue recognition, determining the nature and timing of satisfaction of performance obligations, estimating variable consideration, determining the stand-alone selling prices of performance obligations, gross versus net revenue recognition, evaluation of customer versus vendor relationships, and other obligations such as sales return reserves and customer incentive programs; the fair value or impairment of goodwill and intangible assets; useful lives of tangible and intangible assets; allowances for doubtful accounts or credit losses; the valuation of inventory, the valuation of deferred income tax assets; the recognition and disclosure of contingent liabilities and stock-based compensation. The Company bases its estimates on historical experience and on various other assumptions that the Company believes to be reasonable under the circumstances. Actual results and outcomes may differ from management’s estimates and assumptions due to risks and uncertainties, including uncertainty in the current economic environment due to the recent outbreak of COVID-19. Principles of Consolidation The condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Comprehensive Income (Loss) The comprehensive loss is equal to the net loss for the Concentrations Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash, cash equivalents and accounts receivable. As of March 31, 2020, two two The Company did not have any customers accounting for 10% or more of the Company’s net accounts receivable as of March 31, 2020 and December 31, 2019. Customers accounting for 10% or more of the Company’s net revenue were as follows: Three Months Ended March 31, 2020 March 31, 2019 Customer B * 11 % Customer C 14 % 12 % * less than 10% Restricted Cash Restricted cash is comprised of cash collateral for outstanding letters of credit related to operating leases of office facilities. As of March 31, 2020, the Company had restricted cash of $1.5 million. As of December 31, 2019, the Company had restricted cash of $1.9 million. Content Licensing The Company licenses content for viewing on The Roku Channel. The licensing arrangements can be for a fixed fee and/or advertising revenue share with specific windows of availability. The Company capitalizes the content fees and records a corresponding liability when the license period begins, the cost of the content is known, and the content is accepted and available for streaming. The Company amortizes licensed content assets into “Cost of Revenue, Platform” over the contractual window of availability . As of March 31, 2020 and December 31, 2019, licensed content that met these requirements were $14.5 million and $1.7 million, respectively, and is recorded in “Prepaid expenses and other current assets” and “Accrued Liabilities.” The increase in the content asset and liability is due to a change in the mix of content licensed and the period over which such content is available for streaming. Recently In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments On January 1, 2020, the Company adopted this guidance using the modified retrospective adoption method and recorded a cumulative-effect adjustment to the beginning balance of accumulated deficit of approximately $1.1 million. The measurement of credit losses for newly recognized financial assets and subsequent changes in the allowance for credit losses are recorded in the statements of The Company also adopted the following ASUs effective January 1, 2020, none of which had a material impact on the Company’s financial position or results of operation.

Revenue	3. REVENUE Revenue disaggregation: The Company’s disaggregated revenues are represented by the two reportable segments discussed in Note 14. The disaggregation is based on the evaluations that are regularly performed by the Chief Operating Decision Maker (“CODM”) for purposes of allocating resources and evaluating financial performance. The Company’s CODM is its Chief Executive Officer. Contract balances: Contract balances include the following (in thousands): As of March 31, 2020 December 31, 2019 Accounts receivable, net $ 295,361 $ 332,673 Contract assets (included in Prepaid expenses and other current assets) $ 4,753 $ 3,588 Deferred revenue: Current 38,457 39,861 Non-current 14,795 15,370 Total deferred revenue $ 53,252 $ 55,231 Accounts receivable are recorded at the amount invoiced, net of an allowance for doubtful accounts, sales returns, and sales incentives. Payment terms can vary by customer and contract. The timing of revenue recognition may differ from the timing of invoicing to customers. Contract assets are created when invoicing occurs subsequent to revenue recognition. Contract assets are transferred to accounts receivable when the right to invoice becomes unconditional. Contract liabilities are included in deferred revenue and reflect consideration invoiced prior to the completion of performance obligations and revenue recognition. Contract assets increased by approximately $1.2 million during the three months ended March 31, 2020 primarily due to an increase in the growth of platform revenue combined with the timing of billing which falls into a subsequent period. Deferred revenue decreased by approximately $2.0 million during the three months ended March 31, 2020 due to the timing of fulfillment of performance obligations. During the three months ended March 31, 2020, the Company recognized revenue of approximately $20.5 million from the amounts deferred as of December 31, 2019. During the three months ended March 31, 2019, the Company recognized revenue of approximately $30.7 million from the amounts deferred as of December 31, 2018. Revenue Allocated to Future Performance Obligations: Revenue allocated to remaining or unsatisfied performance obligations represents estimated revenue that has not yet been recognized which includes unearned revenue and amounts that will be invoiced and recognized as revenue in future periods. Estimated contracted revenue was $208.7 million 57

Fair Value	7. FAIR VALUE The Company’s financial assets measured at fair value are as follows (in thousands): March 31, 2020 December 31, 2019 Fair Value Level 1 Fair Value Level 1 Assets: Cash and cash equivalents: Cash $ 586,507 $ 586,507 $ 463,820 $ 463,820 Money market funds 1,787 1,787 51,659 51,659 Restricted cash 1,539 1,539 1,854 1,854 Total assets measured and recorded at fair value $ 589,833 $ 589,833 $ 517,333 $ 517,333 Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal market (or most advantageous market, in the absence of a principal market) for the asset or liability in an orderly transaction between market participants at the measurement date. In measuring fair value, the Company utilizes a fair value hierarchy that prioritizes the inputs used and maximizes the use of observable inputs and minimizes the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: Level 1 —Quoted prices in active markets for identical assets or liabilities. Financial assets and liabilities measured using Level 1 inputs include cash equivalents, accounts receivable, prepaid expenses, accounts payable and accrued liabilities. The Company considers all highly liquid investments purchased with an original or remaining maturity of 90 days or less at the date of purchase to be cash equivalents. The Company measured money market funds of $1.8 million and $51.7 million as cash equivalents as of March 31, 2020 and December 31, 2019, respectively, using Level 1 inputs. Level 2 —Observable inputs other than quoted prices included within Level 1, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are observable or are derived principally from, or corroborated by, observable market data by correlation or other means. The Company did not have Level 2 instruments at March 31, 2020 and December 31, 2019. Level 3 —Unobservable inputs that are supported by little or no market activity, are significant to the fair value of the assets or liabilities and reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The Company did not have Level 3 instruments at March 31, 2020 and December 31, 2019. Assets and liabilities that are measured at fair value on a non-recurring basis Non-financial assets such as goodwill, intangible assets, property, plant, and equipment and operating lease right-of-use assets are evaluated for impairment and adjusted to fair value using Level 3 inputs, only when impairment is recognized. There were no indicators of impairment that required a fair value analysis during the three months ended March 31, 2020. The Company recorded an impairment of $0.9 million for certain operating lease right-of-use assets during the year ended December 31, 2019.

Income Taxes	12. INCOME TAXES Income tax benefit for the three months ended March 31, 2020 and 2019 was $0.2 million and $0.1 million, respectively, primarily attributable to foreign income taxes and state minimum taxes. A valuation allowance is provided when it is more likely than not that some portion of the deferred tax assets will not be realized through future operations. As a result of the Company’s analysis of all available objective evidence, both positive and negative, as of March 31, 2020, management believes it is more likely than not that the deferred tax assets will not be fully realizable. Accordingly, the Company has provided a full valuation allowance against its deferred tax assets with the exception of deferred tax assets related to foreign entities in the U.K., China, India, Netherlands, and Denmark. The primary difference between the effective tax rate and the statutory tax rate relates to the valuation allowance on the Company’s U.S. losses.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, filed with the SEC on March 2, 2020 (the “Annual Report”). The condensed consolidated balance sheet as of December 31, 2019 has been derived from the audited consolidated financial statements as of that date but does not include all of the information and footnotes included in the Company’s Annual Report. The interim financial information is unaudited, but reflects all normal recurring adjustments that are, in the opinion of management, necessary to fairly present the information set forth herein. The results of operations for the three months ended March 31, 2020 are not necessarily indicative of the operating results to be expected for the full year or any future periods. The Company adopted Accounting Standard Codification Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, (“ASC 326”) Credit losses for accounts receivable: The Company maintains an allowance for doubtful accounts to reserve for expected uncollectible accounts receivable. The Company assess collectability by reviewing accounts receivable on a collective basis where similar characteristics exist and on an individual basis when the Company identifies specific customers with known disputes or collectability issues. The Company regularly reviews the allowance by considering historical collectability based on past due status, credit quality, and makes judgments about the creditworthiness of customers based on ongoing credit evaluations. The Company also considers customer-specific information and current economic conditions that may affect a customer’s ability to pay. For the three months ended March 31, 2020, the Company’s assessment of its accounts receivable considered the business and market disruptions caused by the novel coronavirus (“COVID-19”) and emerging credit and collectability trends. The continued volatility in market conditions and evolving shifts in credit trends can be difficult to predict causing volatility that may have a material impact on our allowance for credit losses. See Note 6, for the detailed activity in allowance for doubtful accounts as of March 31, 2020 and December 31, 2019.
Use of Estimates	Use of Estimates The preparation of the Company’s consolidated financial statements in accordance with U.S. GAAP requires management to make certain estimates, judgements, and assumptions that affect the reported amounts of assets, liabilities, net revenue and expenses. Significant items subject to such estimates and assumptions include: for revenue recognition, determining the nature and timing of satisfaction of performance obligations, estimating variable consideration, determining the stand-alone selling prices of performance obligations, gross versus net revenue recognition, evaluation of customer versus vendor relationships, and other obligations such as sales return reserves and customer incentive programs; the fair value or impairment of goodwill and intangible assets; useful lives of tangible and intangible assets; allowances for doubtful accounts or credit losses; the valuation of inventory, the valuation of deferred income tax assets; the recognition and disclosure of contingent liabilities and stock-based compensation. The Company bases its estimates on historical experience and on various other assumptions that the Company believes to be reasonable under the circumstances. Actual results and outcomes may differ from management’s estimates and assumptions due to risks and uncertainties, including uncertainty in the current economic environment due to the recent outbreak of COVID-19.
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and include the accounts of the Company and its wholly-owned subsidiaries.

Content Licensing	Content Licensing The Company licenses content for viewing on The Roku Channel. The licensing arrangements can be for a fixed fee and/or advertising revenue share with specific windows of availability. The Company capitalizes the content fees and records a corresponding liability when the license period begins, the cost of the content is known, and the content is accepted and available for streaming.

Fair Value	The Company’s financial assets measured at fair value are as follows (in thousands): March 31, 2020 December 31, 2019 Fair Value Level 1 Fair Value Level 1 Assets: Cash and cash equivalents: Cash $ 586,507 $ 586,507 $ 463,820 $ 463,820 Money market funds 1,787 1,787 51,659 51,659 Restricted cash 1,539 1,539 1,854 1,854 Total assets measured and recorded at fair value $ 589,833 $ 589,833 $ 517,333 $ 517,333 Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal market (or most advantageous market, in the absence of a principal market) for the asset or liability in an orderly transaction between market participants at the measurement date. In measuring fair value, the Company utilizes a fair value hierarchy that prioritizes the inputs used and maximizes the use of observable inputs and minimizes the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: Level 1 —Quoted prices in active markets for identical assets or liabilities. Financial assets and liabilities measured using Level 1 inputs include cash equivalents, accounts receivable, prepaid expenses, accounts payable and accrued liabilities. The Company considers all highly liquid investments purchased with an original or remaining maturity of 90 days or less at the date of purchase to be cash equivalents. The Company measured money market funds of $1.8 million and $51.7 million as cash equivalents as of March 31, 2020 and December 31, 2019, respectively, using Level 1 inputs. Level 2 —Observable inputs other than quoted prices included within Level 1, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are observable or are derived principally from, or corroborated by, observable market data by correlation or other means. The Company did not have Level 2 instruments at March 31, 2020 and December 31, 2019. Level 3 —Unobservable inputs that are supported by little or no market activity, are significant to the fair value of the assets or liabilities and reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The Company did not have Level 3 instruments at March 31, 2020 and December 31, 2019. Assets and liabilities that are measured at fair value on a non-recurring basis Non-financial assets such as goodwill, intangible assets, property, plant, and equipment and operating lease right-of-use assets are evaluated for impairment and adjusted to fair value using Level 3 inputs, only when impairment is recognized. There were no indicators of impairment that required a fair value analysis during the three months ended March 31, 2020. The Company recorded an impairment of $0.9 million for certain operating lease right-of-use assets during the year ended December 31, 2019.
