Accounting Policies [Abstract]
Business Description and Significant Accounting Policies	Business Description and Significant Accounting Policies Business Description Glowpoint, Inc. (“ Glowpoint, ” “ we, ” “ us, ” or the “ Company ”) is a managed service provider of video collaboration and network applications. Our services are designed to provide a comprehensive suite of automated and concierge applications to simplify the user experience and expedite the adoption of video as the primary means of collaboration. Our customers include Fortune 1000 companies, along with small and medium sized enterprises in a variety of industries. We market our services globally through a multi-channel sales approach that includes direct sales and channel partners. The Company was formed as a Delaware corporation in May 2000. The Company operates in one segment and therefore segment information is not presented. Principles of Consolidation The condensed consolidated financial statements include the accounts of Glowpoint and our 100% -owned subsidiary, GP Communications, LLC, whose business function is to provide interstate telecommunications services for regulatory purposes. All material inter-company balances and transactions have been eliminated in consolidation. Basis of Presentation The Company's fiscal year ends on December 31 of each calendar year. The accompanying interim condensed consolidated financial statements are unaudited and have been prepared on substantially the same basis as our annual consolidated financial statements for the fiscal year ended December 31, 2017 . In the opinion of the Company's management, these interim condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of our financial position, results of operations and cash flows for the periods presented. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from these estimates. The December 31, 2017 year-end condensed consolidated balance sheet data in this document were derived from audited consolidated financial statements and does not include all of the disclosures required by U.S. generally accepted accounting principles. These condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements as of and for the fiscal year ended December 31, 2017 and notes thereto included in the Company's fiscal 2017 Annual Report on Form 10-K, filed with the Securities and Exchange Commission on March 7, 2018 (the “ 2017 10-K”). The results of operations and cash flows for the interim periods included in these condensed consolidated financial statements are not necessarily indicative of the results to be expected for any future period or the entire fiscal year. Significant Accounting Policies The significant accounting policies used in preparation of these condensed consolidated financial statements are disclosed in our 2017 10-K. Adopted Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (ASU) 2014-09 (Topic 606) " Revenue from Contracts with Customers ." Topic 606 supersedes the revenue recognition requirements in Accounting Standards Codification Topic 605 “ Revenue Recognition ” (Topic 605), and requires entities to recognize revenue when control of promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. On January 1, 2018, we adopted Topic 606 using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under Accounting Standards Codification Topic 605. We did not record an adjustment to opening accumulated deficit as of January 1, 2018 as the cumulative impact of adopting Topic 606 was not material. The costs associated with obtaining a customer contract were previously expensed in the period they were incurred. Under Topic 606, these payments are deferred on our consolidated balance sheet and amortized over the expected life of the customer contract. The impact to sales and marketing expense for the three months ended March 31, 2018 was not material as a result of applying Topic 606. In August 2016, the FASB issued ASU No. 2016-15, which amends ASC 230, to clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows. The FASB issued ASU 2016-15 with the intent of reducing diversity in practice with respect to eight types of cash flows. This guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We have adopted this guidance effective January 1, 2018, and this guidance did not have a material impact on our consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, which clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. ASU 2017-09 will reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications. Under ASU 2017-09, an entity will not apply modification accounting to a share-based payment award if the award's fair value, vesting conditions and classification as an equity or liability instrument are the same immediately before and after the change. ASU 2017-09 will be applied prospectively to awards modified on or after the adoption date. We have adopted this guidance effective January 1, 2018, and this guidance did not have a material impact on our consolidated financial statements. Recently Issued Accounting Pronouncements In February 2016 the FASB issued ASU 2016-02, “Leases” . The ASU introduces a lessee model that results in most leases impacting the balance sheet. The ASU addresses other concerns related to the current leases model. Under ASU 2016-02, lessees will be required to recognize for all leases with terms longer than 12 months, at the commencement date of the lease, a lease liability, which is a lessee’s obligation to make lease payments arising from a lease measured on a discounted basis, and a right-to-use asset, which is an asset that represents the lessee’s right to use or control the use of a specified asset for the lease term. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition. The update is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. While we continue to evaluate the effect of adopting this guidance on our consolidated financial statements and related disclosures, we expect our operating leases, as disclosed in Note 10, will be subject to the new standard. We will recognize right-of-use assets and operating lease liabilities on our balance sheet upon adoption, which will increase our total assets and liabilities.

Liquidity and Going Concern

Liquidity and Going Concern	3 Months Ended
	Mar. 31, 2018
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Liquidity and Going Concern	Liquidity and Going Concern As of March 31, 2018 , we had $3,068,000 of cash, working capital of $3,789,000 and no debt. For the three months ended March 31, 2018 , we incurred a net loss of $1,285,000 and used $472,000 of net cash in operating activities. During the three months ended March 31, 2018 and the year ended December 31, 2017 , a substantial portion of our cash flow from operations has been dedicated to the payment of interest on our then-existing indebtedness, thereby reducing our ability to use our cash flow to fund our operations, capital expenditures and investments in sales and marketing. For the three months ended March 31, 2018 and 2017 , our cash flow from operations was reduced by $316,000 and $266,000 , respectively, for interest payments on our then-existing indebtedness. During the three months ended March 31, 2018 , the Company completed a series of transactions (each of which is described further in Notes 6 and 7 below, as applicable) that improved our financial position and reduced the outstanding principal on our debt obligations from $1.8 million as of December 31, 2017 to $0 as of March 31, 2018 . The following is a summary of these transactions: • On January 25, 2018, the Company closed a registered direct offering of 1,750 shares of our 0% Series C Convertible Preferred Stock (the “Series C Preferred Stock”) for net proceeds of $1,527,000 (the “Series C Offering”). • On January 26, 2018, the Company terminated the Business Loan and Security Agreement, dated July 31, 2017, by and between the Company and Super G Capital LLC (“Super G”), along with the accompanying Warrant to Purchase Shares of Common Stock, dated July 31, 2017, and paid off all remaining debt obligations with Super G (“the Super G Payoff”). • During the three months ended March 31, 2018 , the Company made total principal payments of $800,000 on the Western Alliance Bank Loan Agreement, resulting in no outstanding debt as of March 31, 2018 . Our capital requirements continue to depend on numerous factors, including the timing and amount of revenue, the expense to deliver our services, expense for sales and marketing, expense for research and development, capital improvements, and the cost involved in protecting our intellectual property rights. The Company believes that, based on our current projection of revenue, expenses, capital expenditures and cash flows, it has sufficient resources to fund its operations for at least the next twelve months following the filing of this Report. However, there is no assurance the Company will be able to accomplish this during this period or in the future following such period. The Company anticipates reduced cash flow from operations and increased levels of capital expenditures in 2018 as compared to 2017, and we believe additional capital may be required to fund investments in product development and sales and marketing as a means to reverse our revenue trends. While we expect to continue to adjust our cost of revenue and other operating expenses to partially offset the impact of revenue declines associated with our legacy services, we believe additional capital may be necessary to fund our obligations. In the event we need access to capital to fund operations or provide growth capital, we would likely need to raise capital in one or more equity offerings. There can be no assurance that we will be successful in raising necessary capital or that any such offering will be on terms acceptable to the Company. If we are unable to raise additional capital that may be needed on terms acceptable to us, it could have a material adverse effect on the Company. The respective lead investors of the 0% Series B Convertible Preferred Stock (the “Series B Preferred Stock”) and the Series C Preferred Stock have certain rights to approve future financings. There can be no assurance that the lead investors will provide the required approvals, which may affect our ability to raise capital, refinance indebtedness or borrow additional funds on terms we deem advisable, or at all. Failure to obtain financing, or obtaining financing on unfavorable terms, could result in a decrease in our stock price, would have a material adverse effect on future operating prospects, and could require us to significantly reduce operations.

Capitalized Software Costs

Capitalized Software Costs	3 Months Ended
	Mar. 31, 2018
Accounting Policies [Abstract]
Capitalized Software Costs	Capitalized Software Costs The Company capitalizes certain costs incurred in connection with developing or obtaining internal-use software. All software development costs have been appropriately accounted for as required by ASC Topic 350-40 “ Intangible – Goodwill and Other – Internal-Use Software ”. Capitalized software costs are included in “Property and equipment, net” on our condensed consolidated balance sheets and are amortized over three to four years. Software costs that do not meet capitalization criteria are expensed as incurred. For the three months ended March 31, 2018 , we capitalized $48,000 of internal-use software costs. For the three months ended March 31, 2018 and 2017 , we amortized $131,000 and $157,000 , respectively, of these costs. During the three months ended March 31, 2018 and 2017 , we recorded no impairment losses related to capitalized software.

Goodwill & Intangibles

Goodwill & Intangibles	3 Months Ended

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill & Intangibles	Goodwill & Intangibles Goodwill is not amortized but is subject to periodic testing for impairment in accordance with ASC Topic 350 “ Intangibles - Goodwill and Other - Testing Indefinite-Lived Intangible Assets for Impairment ”. We test goodwill for impairment on an annual basis on September 30 of each year or more frequently if events occur or circumstances change indicating that the fair value of the goodwill may be below its carrying amount. As of March 31, 2018 , the Company considered the declines in our revenue and stock price to be a triggering event for an interim goodwill impairment test. The Company operates as a single reporting unit and used market-based approaches to determine the fair value of the reporting unit. These approaches used quoted market prices in active markets and revenue multiples for comparable companies. As of March 31, 2018 , the carrying amount of our reporting unit exceeded its fair value; therefore, the Company recorded a goodwill impairment charge of $650,000 in the three months ended March 31, 2018 . This charge is recognized as “Impairment charges” on our Condensed Consolidated Statements of Operations. The remaining goodwill balance as of March 31, 2018 was $7,100,000 . The continued future decline of our revenue, cash flows and/or stock price may give rise to a triggering event that may require the Company to record additional impairment charges on goodwill in the future. The Company assesses the impairment of purchased intangible assets subject to amortization when events and circumstances indicate that the carrying value of the assets might not be recoverable. Fair value of our intangible assets is determined using the relief from royalty methodology. This approach involves two steps: (a) estimating reasonable royalty rates for each intangible asset and (b) applying these royalty rates to a net revenue stream and discounting the resulting cash flows to determine fair value. This fair value is then compared with the carrying value of each intangible asset. If the carrying value of the intangible asset is greater than its implied fair value, an impairment in the amount of the excess is recognized and charged to operations. The determination of related estimated useful lives and whether or not these assets are impaired involves significant judgments, related primarily to the future profitability and/or future value of the assets. Changes in the Company’s strategic plan and/or other-than-temporary changes in market conditions could significantly impact these judgments and could require adjustments to recorded asset balances. Long-lived assets are evaluated for impairment at least annually, as well as whenever an event or change in circumstances has occurred that could have a significant adverse effect on the fair value of long-lived assets. The Company performed an evaluation of intangible assets as of March 31, 2018 and determined that the fair value of the long-lived assets exceeded the carrying value, therefore no impairment charges were required for the three months ended March 31, 2018 .

The Western Alliance Bank Loan Agreement provided the Company with up to a total of $1,500,000 of revolving loans (the “A/R Revolver”). The maximum amount available under the A/R Revolver was limited to the lesser of (x) $1,500,000 and (y) an amount equal to the borrowing base. The borrowing base included 85% of the Company’s eligible accounts receivable plus a non-formula amount (which was $400,000 at December 31, 2017 , and which stepped down to $200,000 on January 1, 2018, and to $0 on April 1, 2018) (“the Non-Formula Amount”). The Western Alliance Bank Loan Agreement provided that all borrowings would bear interest at the prime rate ( 4.75% as of March 31, 2018 ) plus 2.25% (or a total of 7.00% as of March 31, 2018 ) per year. The prime rate was subject to a floor of 4.00% . Interest payments on the outstanding borrowings were due monthly. On July 31, 2017, the Company received a loan in an amount equal to $1,100,000 under the Western Alliance Bank Loan Agreement, consisting of $500,000 based on 85% of eligible accounts receivable and $600,000 of Non-Formula Amount. During the three months ended March 31, 2018 , the Company made total principal payments of $800,000 on the A/R Revolver (including $400,000 on the Non-Formula Amount). As of March 31, 2018 , there were no outstanding borrowings on the A/R Revolver and we had availability of $764,000 . All loans under the A/R Revolver were to mature on July 31, 2019 (unless such loans are not supported by the borrowing base, in which case any loans exceeding the borrowing base must be immediately repaid). As of March 31, 2018 , the Company was in compliance with all required covenants under the Western Alliance Bank Loan Agreement. On May 8, 2018 , the Company terminated the Western Alliance Bank Loan Agreement. Super G Loan Agreement and Warrant On July 31, 2017, the Company and its subsidiary entered into a Business Loan and Security Agreement with Super G Capital, LLC (“Super G”), as lender (the “Super G Loan Agreement”) and received a term loan from Super G in an amount equal to $1,100,000 (the “Super G Loan”). Borrowings under the Super G Loan Agreement were to be repaid in installments (including interest) of $33,000 per month in the first 3 months following closing and approximately $68,600 per month in months four through twenty-four following closing, for total payments of $1,540,000 . The effective interest rate of the Super G Loan was approximately 33% . On July 31, 2017, the Company also issued a warrant that entitled Super G to purchase 550,000 shares of the Company’s common stock at an exercise price of $0.30 per share (the “Super G Warrant”). The Super G Warrant had a three year term and if the profit on such warrants was not equal to at least $165,000 over the term of the warrants, at the end of the three year term, the Company was required to pay an exit fee equal to the difference between $165,000 and the amount of profit recognized. During the three months ended March 31, 2018 , no warrants were exercised. The $165,000 fair value of this warrant was recorded as a derivative liability and as a discount to the carrying amount of the debt as of December 31, 2017 . On January 26, 2018, the Company and Super G entered into a payoff letter that terminated the Super G Loan Agreement and the Super G Warrant in exchange for total cash payments from the Company of $1,269,000 (the “Super G Payoff”). The total obligations to Super G at the time of the Super G Payoff was $1,434,000 , including principal, accrued and remaining interest due over the term of the Super G Loan, and the Super G Warrant Liability. Therefore, the Company recorded a gain on extinguishment of the debt of $165,000 , which is recorded in “Interest and Other Expense, Net” on our Condensed Consolidated Statements of Operations. In connection with the Super G Payoff, the related warrant liability and corresponding debt discount were eliminated during the three months ended March 31, 2018 . As of March 31, 2018 , there are no outstanding obligations related to the Super G Loan. The total debt discount on the Western Alliance Bank A/R Revolver and Super G Loan was $339,000 , comprised of $174,000 of debt issuance costs and $165,000 related to the Super G Warrant. This debt discount was being amortized to interest expense using the effective interest method over the term of the debt. During the three months ended March 31, 2018 , the Company amortized $269,000 of the debt discount, which is recorded in “Interest and Other Expense, Net” on our Condensed Consolidated Statements of Operations. As of March 31, 2018 , there is no remaining unamortized debt discount.

Equity [Abstract]
Preferred Stock	Preferred Stock Our Certificate of Incorporation authorizes us to issue up to 5,000,000 shares of preferred stock. As of March 31, 2018 , there were: (i) 100 shares of Perpetual Series B-1 Preferred Stock authorized and no shares issued or outstanding; (ii) 7,500 shares of Series A-2 Convertible Preferred Stock authorized and 32 shares issued and outstanding (the “Series A-2 Preferred Stock”); (iii) 2,800 shares of Series B Preferred Stock authorized and 375 shares issued and outstanding; (iv) 1,750 shares of Series C Preferred Stock authorized and 1,275 shares issued and outstanding; (v) 4,000 shares of Series D Convertible Preferred Stock authorized and no shares issued or outstanding; and (vi) 100 shares of Perpetual Series B Preferred Stock authorized and no shares issued or outstanding. Series A-2 Preferred Stock Each share of Series A-2 Preferred Stock has a stated value of $7,500 per share (the “A-2 Stated Value”), a liquidation preference equal to the A-2 Stated Value, and is convertible at the holder’s election into common stock at a conversion price per share of $2.16 as of March 31, 2018 . Therefore, each share of Series A-2 Preferred Stock is convertible into 3,472 shares of common stock as of March 31, 2018 . The conversion price is subject to adjustment upon the occurrence of certain events set forth in our Certificate of Incorporation. During the three months ended March 31, 2018 , the Series C Offering resulted in an adjustment to the Series A-2 Preferred Stock conversion price from $2.40 to $2.16 per share. The Series A-2 Preferred Stock is subordinate to the Series B-1 Preferred Stock but senior to all other classes of equity, has weighted average anti-dilution protection and, since January 1, 2013, has been entitled to cumulative dividends at a rate of 5% per annum, payable quarterly, based on the A-2 Stated Value and payable at the option of the holder in cash or through the issuance of a number of additional shares of Series A-2 Preferred Stock with an aggregate liquidation preference equal to the dividend amount payable on the applicable dividend payment date. As of March 31, 2018 , the Company has recorded $62,000 in accrued dividends in “Accrued expenses and other liabilities” on the accompanying Condensed Consolidated Balance Sheet related to the remaining Series A-2 Preferred Stock outstanding. The Company, at our option, may redeem all or a portion of the Series A-2 Preferred Stock in cash at a price per share of $8,250 per share (equal to $7,500 per share multiplied by 110% ) plus all accrued and unpaid dividends. Series B Preferred Stock In October 2017, the Company closed a registered direct offering of 2,800 shares of its Series B Preferred Stock for total gross proceeds to the Company of $2,800,000 . The shares of Series B Preferred Stock were sold at a price equal to their stated value of $1,000 per share and are convertible into shares of the Company’s common stock at a conversion price of $0.28 per share. During the three months ended March 31, 2018 , 75 shares of Series B Preferred Stock were converted to 268,000 shares of the Company’s common stock. As of March 31, 2018 , 375 shares of Series B Preferred Stock remain issued and outstanding. The Series B Preferred Stock is pari passu with the Company’s issued and outstanding shares of Series C Preferred Stock. Subject to certain exceptions, the Company has agreed to provide the holders of Series B Preferred Stock a right of participation for up to 100% of any future offering of its common stock or other securities or equity linked debt obligations until October 2019. In addition, the Company agreed to expand the size of the Company’s board of directors to six members and to appoint a new independent director agreeable to the lead investor in the offering (the “Lead Investor”). Subject to limited exceptions, for as long as at least 333 shares of Series B Preferred Stock remain outstanding and unconverted (subject to adjustment for stock splits, stock dividends, recapitalizations, reorganizations, reclassifications, combinations and subdivisions or similar events occurring after the date of the Purchase Agreement with respect to the Series B Preferred Stock), the Company may not issue any common stock or convertible securities (or modify any of the foregoing that may be outstanding) to any person, or incur any debt, without the express written consent of the Lead Investor. In addition, the Company has agreed that it will not enter into certain “fundamental transactions,” including transactions constituting a change of control of the Company, certain reorganization transactions or a sale of all or substantially all of the Company’s assets, except as pursuant to written agreements in form and substance satisfactory to the holders of a majority of the outstanding shares of Series B Preferred Stock including the Lead Investor and on terms with respect to the Series B Preferred Stock as set forth in the Certificate of Designation of Rights, Powers, Preferences, Privileges and Restrictions of the Series B Preferred Stock. Series C Offering On January 25, 2018, the Company closed a registered direct offering of 1,750 shares of its Series C Preferred Stock for total gross proceeds to the Company of $1,750,000 . The shares of Series C Preferred Stock were sold at a price equal to their stated value of $1,000 per share and are convertible into shares of the Company’s common stock at a conversion price of $0.30 per share. The net proceeds to us from the sale of our securities in this offering were $1,527,000 after deducting offering expenses paid by us. During the three months ended March 31, 2018 , 475 shares of Series C Preferred Stock were converted to 1,583,000 shares of the Company’s common stock. As of March 31, 2018 , 1,275 shares of Series C Preferred Stock remain issued and outstanding. The Series C Preferred Stock is pari passu with the Company’s issued and outstanding shares of Series B Preferred Stock. Subject to certain exceptions, the Company has agreed to provide the purchasers, during the period that the purchasers continue to hold Series C Preferred Stock, a right of participation for up to 100% of any future offering of its common stock or other securities or equity linked debt obligations until January 2020. Subject to limited exceptions, for as long as at least $500,000 of stated value of Series C Preferred Stock remain outstanding and unconverted (subject to adjustment for stock splits, stock dividends, recapitalizations, reorganizations, reclassifications, combinations and subdivisions or similar events occurring after the date of the Purchase Agreement with respect to the Series C Preferred Stock), the Company shall not issue any common stock or convertible securities (or modify any of the foregoing that may be outstanding) to any person at a price per share less than $0.30 , or incur any debt, without the express written consent of the Lead Investor. In addition, the Company has agreed that it will not enter into certain “fundamental transactions,” including transactions constituting a change of control of the Company, certain reorganization transactions or a sale of all or substantially all of the Company’s assets, except as pursuant to written agreements in form and substance satisfactory to the holders of a majority of the outstanding shares of Series C Preferred Stock including the Lead Investor and on terms with respect to the Series C Preferred Stock as set forth in the Certificate of Designation of Rights, Powers, Preferences, Privileges and Restrictions of the Series C Preferred Stock. In accordance with ASC Topic 815, we evaluated whether our convertible preferred stock contains provisions that protect holders from declines in our stock price or otherwise could result in modification of the exercise price and/or shares to be issued under the respective preferred stock agreements based on a variable that is not an input to the fair value of a “fixed-for-fixed” option and require a derivative liability. The Company determined no derivative liability is required under ASC Topic 815 with respect to our convertible preferred stock. A contingent beneficial conversion amount is required to be calculated and recognized when and if the adjusted $2.16 conversion price of the Series A-2 Preferred Stock is adjusted to reflect a down round stock issuance that reduces the conversion price below the $1.16 fair value of the common stock on the issuance date of the Series A-2 Preferred Stock.

Earnings Per Share [Abstract]
Net Loss Per Share	Net Loss Per Share Basic net loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. The weighted-average number of shares of common stock outstanding does no t include any potentially dilutive securities or unvested restricted stock. Unvested restricted stock, although classified as issued and outstanding at March 31, 2018 and 2017 , is considered contingently returnable until the restrictions lapse and will not be included in the basic net loss per share calculation until the shares are vested. Unvested restricted stock does not contain non-forfeitable rights to dividends and dividend equivalents. Unvested RSUs are not included in calculations of basic net loss per share, as they are not considered issued and outstanding at time of grant. Diluted net loss per share is computed by giving effect to all potential shares of common stock, including stock options, preferred stock, RSUs, and unvested restricted stock, to the extent they are dilutive. For the three months ended March 31, 2018 and 2017 , all such common stock equivalents have been excluded from diluted net loss per share as the effect to net loss per share would be anti-dilutive (decrease our net loss per share). The following table sets forth the computation of the Company’s basic and diluted net loss per share (in thousands, except per share data): Three Months Ended March 31, 2018 2017 Numerator: Net loss $ (1,285 ) $ (668 ) Less: preferred stock dividends 3 3 Net loss attributable to common stockholders $ (1,288 ) $ (671 ) Denominator: Weighted-average number of shares of common stock for basic and diluted net loss per share 46,232 36,181 Basic and diluted net loss per share $ (0.03 ) $ (0.02 ) The weighted-average number of shares for the three months ended March 31, 2018 and 2017 includes 988,000 and 517,000 shares of vested RSUs, respectively, as discussed in Note 8. The following table represents the potential shares that were excluded from the computation of weighted-average number of shares of common stock in computing the diluted net loss per share for the periods presented because including them would have had an anti-dilutive effect (in thousands): Three Months Ended March 31, 2018 2017 Unvested restricted stock units 742 2,938 Unvested restricted stock awards 113 354 Outstanding stock options 1,192 1,222 Shares of common stock issuable upon conversion of Series A-2 Preferred 79 79 Shares of common stock issuable upon conversion of Series B Preferred 1,339 — Shares of common stock issuable upon conversion of Series C Preferred 4,250 —

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements include the accounts of Glowpoint and our 100% -owned subsidiary, GP Communications, LLC, whose business function is to provide interstate telecommunications services for regulatory purposes. All material inter-company balances and transactions have been eliminated in consolidation.
Basis of Presentation	Basis of Presentation The Company's fiscal year ends on December 31 of each calendar year. The accompanying interim condensed consolidated financial statements are unaudited and have been prepared on substantially the same basis as our annual consolidated financial statements for the fiscal year ended December 31, 2017 . In the opinion of the Company's management, these interim condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of our financial position, results of operations and cash flows for the periods presented. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from these estimates.
Adopted Accounting Standards and Recently Issued Accounting Pronouncements	Adopted Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (ASU) 2014-09 (Topic 606) " Revenue from Contracts with Customers ." Topic 606 supersedes the revenue recognition requirements in Accounting Standards Codification Topic 605 “ Revenue Recognition ” (Topic 605), and requires entities to recognize revenue when control of promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. On January 1, 2018, we adopted Topic 606 using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under Accounting Standards Codification Topic 605. We did not record an adjustment to opening accumulated deficit as of January 1, 2018 as the cumulative impact of adopting Topic 606 was not material. The costs associated with obtaining a customer contract were previously expensed in the period they were incurred. Under Topic 606, these payments are deferred on our consolidated balance sheet and amortized over the expected life of the customer contract. The impact to sales and marketing expense for the three months ended March 31, 2018 was not material as a result of applying Topic 606. In August 2016, the FASB issued ASU No. 2016-15, which amends ASC 230, to clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows. The FASB issued ASU 2016-15 with the intent of reducing diversity in practice with respect to eight types of cash flows. This guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We have adopted this guidance effective January 1, 2018, and this guidance did not have a material impact on our consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, which clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. ASU 2017-09 will reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications. Under ASU 2017-09, an entity will not apply modification accounting to a share-based payment award if the award's fair value, vesting conditions and classification as an equity or liability instrument are the same immediately before and after the change. ASU 2017-09 will be applied prospectively to awards modified on or after the adoption date. We have adopted this guidance effective January 1, 2018, and this guidance did not have a material impact on our consolidated financial statements. Recently Issued Accounting Pronouncements In February 2016 the FASB issued ASU 2016-02, “Leases” . The ASU introduces a lessee model that results in most leases impacting the balance sheet. The ASU addresses other concerns related to the current leases model. Under ASU 2016-02, lessees will be required to recognize for all leases with terms longer than 12 months, at the commencement date of the lease, a lease liability, which is a lessee’s obligation to make lease payments arising from a lease measured on a discounted basis, and a right-to-use asset, which is an asset that represents the lessee’s right to use or control the use of a specified asset for the lease term. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition. The update is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. While we continue to evaluate the effect of adopting this guidance on our consolidated financial statements and related disclosures, we expect our operating leases, as disclosed in Note 10, will be subject to the new standard. We will recognize right-of-use assets and operating lease liabilities on our balance sheet upon adoption, which will increase our total assets and liabilities.
Capitalized Software Costs	Capitalized Software Costs The Company capitalizes certain costs incurred in connection with developing or obtaining internal-use software. All software development costs have been appropriately accounted for as required by ASC Topic 350-40 “ Intangible – Goodwill and Other – Internal-Use Software ”. Capitalized software costs are included in “Property and equipment, net” on our condensed consolidated balance sheets and are amortized over three to four years. Software costs that do not meet capitalization criteria are expensed as incurred.
Goodwill & Intangible Assets	Goodwill & Intangibles Goodwill is not amortized but is subject to periodic testing for impairment in accordance with ASC Topic 350 “ Intangibles - Goodwill and Other - Testing Indefinite-Lived Intangible Assets for Impairment ”. We test goodwill for impairment on an annual basis on September 30 of each year or more frequently if events occur or circumstances change indicating that the fair value of the goodwill may be below its carrying amount. As of March 31, 2018 , the Company considered the declines in our revenue and stock price to be a triggering event for an interim goodwill impairment test. The Company operates as a single reporting unit and used market-based approaches to determine the fair value of the reporting unit. These approaches used quoted market prices in active markets and revenue multiples for comparable companies. As of March 31, 2018 , the carrying amount of our reporting unit exceeded its fair value; therefore, the Company recorded a goodwill impairment charge of $650,000 in the three months ended March 31, 2018 . This charge is recognized as “Impairment charges” on our Condensed Consolidated Statements of Operations. The remaining goodwill balance as of March 31, 2018 was $7,100,000 . The continued future decline of our revenue, cash flows and/or stock price may give rise to a triggering event that may require the Company to record additional impairment charges on goodwill in the future. The Company assesses the impairment of purchased intangible assets subject to amortization when events and circumstances indicate that the carrying value of the assets might not be recoverable. Fair value of our intangible assets is determined using the relief from royalty methodology. This approach involves two steps: (a) estimating reasonable royalty rates for each intangible asset and (b) applying these royalty rates to a net revenue stream and discounting the resulting cash flows to determine fair value. This fair value is then compared with the carrying value of each intangible asset. If the carrying value of the intangible asset is greater than its implied fair value, an impairment in the amount of the excess is recognized and charged to operations. The determination of related estimated useful lives and whether or not these assets are impaired involves significant judgments, related primarily to the future profitability and/or future value of the assets. Changes in the Company’s strategic plan and/or other-than-temporary changes in market conditions could significantly impact these judgments and could require adjustments to recorded asset balances. Long-lived assets are evaluated for impairment at least annually, as well as whenever an event or change in circumstances has occurred that could have a significant adverse effect on the fair value of long-lived assets.
