| Nature of Operations and Continuance of Business [Text Block] | 1. Nature of Operations and Continuance of Business TechMedia Advertising, Inc. (the "Company") was incorporated in the State of Nevada on January 30, 2007 under the name Ultra Care, Inc. On February 17, 2009, the Company merged with its wholly owned subsidiary, TechMedia Advertising, Inc., in order to effect a name change from Ultra Care, Inc. to TechMedia Advertising, Inc. The Company is currently exploring potential business opportunities in different markets. These condensed financial statements have been prepared on a going concern basis, which implies the Company will continue to realize its assets and discharge its liabilities in the normal course of business. As at October 31, 2018, the Company has no revenues, has a working capital deficiency of $282,080, and has an accumulated deficit of $5,883,296. The continuation of the Company as a going concern is dependent upon the continued financial support from its shareholders, the ability of the Company to obtain necessary equity financing to continue to develop its business and ultimately on the attainment of profitable operations. The Company is in the process of arranging additional capital financing that may assist in addressing these issues; however, these factors continue to raise substantial doubt regarding the Company’s ability to continue as a going concern. These condensed financial statements do not include any adjustments to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern. |

| Significant Accounting Policies [Text Block] | 2. Significant Accounting Policies (a) Basis of Presentation The accompanying unaudited condensed financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. However, in the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Results of operations for the interim periods are not necessarily indicative of the operating results to be attained in the entire fiscal year. (b) Use of Estimates The preparation of these financial statements in conformity with U.S. GAAP 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company regularly evaluates estimates and assumptions related to deferred income tax asset valuation allowances. The Company bases its estimates and assumptions on current facts, historical experience and various other factors that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the accrual of costs and expenses that are not readily apparent from other sources. The actual results experienced by the Company may differ materially and adversely from the Company’s estimates. To the extent there are material differences between the estimates and the actual results, future results of operations will be affected. (c) Financial Instruments and Fair Value Measures ASC 820, “Fair Value Measurements and Disclosures” (“ASC 820”), requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. ASC 820 prioritizes the inputs into three levels that may be used to measure fair value: Level 1 Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2 Level 2 applies to assets or liabilities for which there are inputs other than quoted prices that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data. Level 3 Level 3 applies to assets or liabilities for which there are no observable inputs to the valuation methodology that are relevant to the measurement of the fair value of the assets or liabilities. The Company’s financial instruments consist of accounts payable and accrued liabilities, and amounts due to related parties, which approximate their current fair values because of their nature and respective maturity dates or durations. (d) Recent Accounting Pronouncements The Company has implemented all new accounting pronouncements that are in effect and that may impact its financial statements and does not believe that there are any other new accounting pronouncements that have been issued that might have a material impact on its financial position or results of operations. |
