Organization, Consolidation and Presentation of Financial Statements [Abstract]
Revenue Recognition	The Company’s revenues and earnings are seasonal in nature, primarily due to its Racing Operations segment. Therefore, revenues and operating results for any interim quarter are generally not indicative of the revenues and operating results for the year and may not be comparable with results for the corresponding period of the previous year. For instance, the Company historically has had fewer live racing days during the first quarter of each year, and the majority of its live racing revenue occurs during the second quarter, with the running of the Kentucky Derby and the Kentucky Oaks. The Company conducted 114 live thoroughbred racing days during the second quarter of 2014, which compares to 124 live thoroughbred racing days during the second quarter of 2013. For the six months ended June 30, 2014, the Company conducted 206 live thoroughbred racing days, which compares to 180 live racing days during the six months ended June 30, 2013. This increase is primarily due to Calder Race Course conducting 29 additional live race days during the first six months of 2014 because of its revised racing calendar, which included a 39-day live winter racing meet during the first quarter of 2014. Furthermore, gaming revenues and earnings have historically been higher during the first quarter due to seasonal revenues from the Company's predominately southern gaming properties.
Discontinued Operations, Policy [Policy Text Block]	During the year ended December 31, 2013, the Company ceased operations of Fight! Magazine, a division of Bluff Media. Fight! Magazine, which was previously a component of the Other Investments segment, and its results of operations for the three months and six months ended June 30, 2013 have been reclassified to discontinued operations.
Comprehensive Income	The Company had no other components of comprehensive income and, as such, comprehensive income is the same as net earnings as presented in the accompanying Condensed Consolidated Statements of Comprehensive Income.
Customer Loyalty Programs	The Company’s customer loyalty programs offer incentives to customers who wager at the Company’s racetracks, through its advance deposit wagering platform, TwinSpires.com, or at its gaming facilities. The TSC Elite program is for pari-mutuel wagering at the Company’s racetracks or through TwinSpires.com. The Player’s Club is offered at the Company’s gaming facilities in Louisiana, Florida, Maine and Mississippi. As of both June 30, 2014 and December 31, 2013, the outstanding reward point liabilities were $2.1 million and were included in accrued expenses.
Promotional Allowances	Promotional allowances, which include the Company’s customer loyalty programs, primarily consist of the retail value of complimentary goods and services provided to guests at no charge. The retail value of these promotional allowances is included in gross revenue and then deducted to arrive at net revenue. During the three months ended June 30, 2014 and 2013, promotional allowances of $8.7 million and $9.1 million, respectively, were included as a reduction to net revenues. During those periods, Online Business promotional allowances were $3.5 million and $3.7 million, respectively. Gaming promotional allowances were $5.0 million and $5.1 million, respectively. Racing Operations promotional allowances were $0.2 million and $0.3 million, respectively. The estimated cost of providing promotional allowances included in operating expenses totaled $2.3 million and $2.5 million for each of the three months ended June 30, 2014 and 2013

Disclosure of accounting policy for any discontinued operations. The results of operations of a component of an entity that either has been disposed of or is classified as held for sale is reported in discontinued operations if both: (a) the operations and cash flows of the component have been (or will be) eliminated from the ongoing operations of the entity as a result of the disposal transaction and (b) the entity will not have any significant continuing involvement in the operations of the component after the disposal transaction. If the entity elects to allocate interest expense to a discontinued operation, it may disclose its accounting policy for this election and describe its method of allocation.

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
