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, 2018. 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.
Leases	Leases The Company determines if an arrangement is a lease at inception. For the Company’s operating leases, the right-of-use (“ROU”) assets represents the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent an obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Since all of the lease agreements do not provide an implicit rate, the Company estimated an incremental borrowing rate in determining the present value of the lease payments. Operating lease expense is recognized on a straight-line basis over the lease term, subject to any changes in the lease or expectations regarding the terms. Variable lease costs such as operating costs and property taxes are expensed as incurred.
Treasury Stock	Treasury Stock Purchases and sales of treasury stock are accounted for using the cost method. Under this method, shares acquired are recorded at the acquisition price directly to the treasury stock account. Upon sale, the treasury stock account is reduced by the original acquisition price of the shares and any difference is recorded in equity, on a first-in first-out basis. This method does not allow the Company to recognize a gain or loss to income from the purchase and sale of treasury stock.
Adopted Accounting Standards and Recently Issued Accounting Pronouncements	Adopted Accounting Standards In February 2016 the FASB issued ASU 2016-02, “Leases (Topic 842),” which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. On January 1, 2019, the Company adopted the new lease standard using the optional transition method under which comparative financial information will not be restated and continue to apply the provisions of the previous lease standard in its annual disclosures for the comparative periods. In addition, the new lease standard provides a number of optional practical expedients in transition. The Company elected the package of practical expedients. As such, the Company did not have to reassess whether expired or existing contracts are or contain a lease; did not have to reassess the lease classifications or reassess the initial direct costs associated with expired or existing leases. The new lease standard also provides practical expedients for an entity's ongoing accounting. The Company elected the short-term lease recognition exemption under which the Company will not recognize ROU assets or lease liabilities, and this includes not recognizing ROU assets or lease liabilities for existing short-term leases. The Company elected the practical expedient to not separate lease and non-lease components for certain classes of assets (office buildings). For leases that qualify as short-term leases, the Company has elected to not apply the balance sheet recognition requirements of Topic 842, and instead we recognize the lease payments in the condensed consolidated statement of operations on a straight-line basis over the lease term. On January 1, 2019, the Company recognized ROU assets and lease liabilities of approximately $99,000 and $111,000, respectively, using an estimated incremental borrowing rate of 7.75%. The ROU assets are recorded in other assets and the lease liabilities are recorded in accrued expenses on the Company’s condensed consolidated balance sheet. In June 2018 the FASB issued ASU 2018-07, “Compensation - Stock Compensation (Topic 718).” The guidance simplifies the accounting for share-based payments to non-employees by aligning it with the accounting for share-based payments to employees, with certain exceptions. The new guidance expands the scope to include share-based payments granted to non-employees in exchange for goods or services used or consumed in an entity’s own operations and supersedes the guidance in ASC 505-50. Effective January 1, 2019, we adopted Topic 718 and this guidance did not have a material impact on our consolidated financial statements. Recently Issued Accounting Pronouncements In June 2016 the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326).” The amendments introduce an impairment model that is based on expected credit losses, rather than incurred losses, to estimate credit losses on certain types of financial instruments (e.g., loans and held-to-maturity securities), including certain off-balance sheet financial instruments (e.g., loan commitments). The expected credit losses should consider historical information, current information, and reasonable and supportable forecasts, including estimates of prepayments, over the contractual term. Financial instruments with similar risk characteristics may be grouped together when estimating expected credit losses. In addition, the amendments provide for a simplified accounting model for purchased financial assets with a more-than-insignificant amount of credit deterioration since their origination. The update is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We believe the effect of adopting this guidance on our consolidated financial statements and related disclosures will not be material.
