summer 2003. The original idea was that users would pay a yearly subscription fee and receive new titles as they became available. Initially, Stardock's own titles along with titles from Strategy First were available. A year later, Stardock replaced the subscription model with a new system called TotalGaming.net in which users could purchase games individually or pay an upfront fee for tokens which allowed them to purchase games at a discount. TotalGaming.net targeted independent game developers rather than the larger publishers. In late 2008, new token purchases were discontinued. In 2008, Stardock announced its third-generation digital distribution platform, Impulse. Stardock's intention was for Impulse to include independent third-party games and major publisher titles and indeed, the service now includes content from a variety of publishers. The platform was sold to GameStop in May 2011. After the sale of Impulse to GameStop and the lack of success in major sales, Stardock's titles have started to appear on rival digital distribution services such as Steam. ThinkDesk ThinkDesk was a productivity application subscription service, launched by Stardock on 14 April 2005 as a utility counterpart to their Object Desktop and TotalGaming.net services. Subscriptions were for one year, after which users could choose to renew or keep the software that they have, including all released upgrades to that date. The service never came out of beta and was discontinued in March 2009. ThinkDesk components were typically downloaded using Impulse, although if purchased separately they could also be downloaded as executable installers. They included: Multiplicity, which allows the control of multiple PCs with a single keyboard and mouse, in a similar manner to a KVM switch KeepSafe, which automatically kept file revisions for selected directories and file types ThinkSync, which synchronized files and folders between hard drives or across the Internet SecureProcess, which allowed only processes defined as safe to run; an anti-virus/anti-spyware component Litigation Stardock has been involved in litigation in relation to their business: In 1998, they were sued by Entrepreneur magazine for use of the trademark name "Entrepreneur" for one of their games. Stardock claimed that their use of this word was not related to the magazine's business, but did not have the money to fight the case—the name was changed to Business Tycoon; a later version was rebranded as The Corporate Machine. In December 2003, TGTSoft sued Stardock and Brad Wardell for declarative relief, claiming that they should be able to
