Segment Reporting Disclosure [Text Block] | Note 17 -Business Segments: Prior to December 23, 2010, ( the Restructuring Transaction date), the Company operated two reportable business segments: ( 1 ) Publishing and ( 2 ) Investment Management. The Publishing segment, the Company's only reportable segment subsequent to the Restructuring Transaction date, produces investment periodicals and related publications (retail and institutional) in both print and digital form, and includes copyright data fees for the Value Line Proprietary Ranking System information and other proprietary information. As more fully described in Note 1 - Organization and Summary of Significant Accounting Policies, the Company deconsolidated its investment management business on December 23, 2010 and therefore no longer reports the investment management operation as a separate business unit. Although VLI continues to receive significant cash flows from these operations through its non-controlling investment in EAM, it no longer considers this to be a reportable business segment due to its lack of control over the operating and financial policies of EAM.
