Subsequent Event [Abstract]
Subsequent Events [Text Block]	Subsequent Event On December 7, 2015, the Company received a notification from the Listing Qualifications Department of Nasdaq indicating that the Company's Class A common stock was not in compliance with Markeplace Rule 5450(a)(1) (the “Minimum Bid Price Rule”) because the minimum bid price of the Company's Class A common stock on the Nasdaq Global Select Market closed below $1.00 per share for 30 consecutive business days. In accordance with Marketplace Rules 5810(c)(3)(A), the Company had 180 calendar days, or until June 6, 2016, for our Class A common stock to regain compliance with the Minimum Bid Price Rule. During the 180 day period, the Company’s Class A common stock continued to trade on the Nasdaq Global Select Market. On June 7, 2016, the Company received a written notification (the "Staff Determination")from Nasdaq stating that because the Company had not regained compliance with the $1.00 minimum bid price requirement for continued listing, the Company’s Class A common stock (listed on The Nasdaq Global Select Market under the symbol “EMMS”) would be subject to delisting unless the Company requested a hearing before a Nasdaq Hearings Panel (the "Panel") on or before June 14, 2016. The Company requested a hearing before the Panel, which stayed any delisting action in connection with the Staff Determination and allowed the continued listing of the Company’s Class A common stock on The Nasdaq Global Select Market until the Panel renders a decision subsequent to the hearing. At the hearing, the Company intends to present a plan to regain compliance with Rule 5450(a)(1) and request that the Panel allow the Company additional time within which to regain compliance. The Company believes that it will be able to present a viable plan to regain compliance because our shareholders are scheduled to vote upon a proposed amendment to our articles of incorporation to permit a one-for-four reverse stock split at our annual meeting on July 7, 2016 and we have already received sufficient votes for the proposal’s adoption. Upon receipt of formal shareholder approval, the reverse stock split is expected to be implemented effective upon the commencement of trading on July 8, 2016. Thus, the Company expects that our Class A common stock will have been trading above $1.00 for ten consecutive trading days on July 21, 2016, the date of our Nasdaq hearing.
