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.
