Mark Cuban disclosed in a 13-D filed this morning that he has a 9.4% stake in Carmike Cinemas (NASDAQ: CKEC).

Unlike Mr. Cuban's personal blog, the 13-D lacks much in the way of color: There is the standard disclosure that he acquired the stake for investment purposes and may buy more or sell some or all depending on his mood.

According to the company, "Carmike Cinemas, Inc. is a U.S. leader in digital cinema and 3-D cinema deployments and one of the nation's largest motion picture exhibitors. As of September 30, 2008, Carmike had 250 theatres with 2,276 screens in 36 states. Carmike's digital cinema footprint reaches 2,147 screens, of which 430 are also equipped with 3-D capability. Carmike's focus for its theatre locations is small to mid-sized communities with populations of fewer than 100,000."

The company has been reporting huge losses as it sinks under the weight of a crippling debt load and economic malaise. But Cuban's one of the smartest people in business, so maybe there's some upside to be had. The shares have lost about 90% of their value since the beginning of 2007.

Celebrities -- they're more than superior human beings, they're money-making machines. If these celebrities were stocks, which would be the shrewd buy?

The shrewd, cantankerous veteran vs. the trash-talking but talented kid -- who would you put your money on?

The veteran would be George Steinbrenner, head of the New York Yankees since 1973. Steinbrenner made his nut in the family shipbuilding business when he bought out the American Ship Building Co. He was always an avid sports fan, even serving as a football coach at Northwestern and Purdue before returning to the business world. His first acquisition, however, the Cleveland Pipers of the American Basketball Association, left him broke. But his taste for the big leagues remained.

Maybe it was the smugness Christian Laettner displayed during my formative years, or the subtle differences between NBA and NCAA Basketball rules, but professional basketball has always been my least favorite of the major sports.

I am impressed, however, with the National Basketball Association's acknowledgment of the digital age. Today, the league announced that it has rolled out a video-download store, at which fans can purchase digital copies of playoff games for $3 a pop. Entire series are available for $13 each, with a full playoff season available for $80.

The league's vice president of interactive services was quoted by the New York Times as saying "great games and surprising results have driven the most popular downloads." Among the heaviest downloads have been the series between the Golden State Warriors and the Dallas Mavericks, as well as last year's final championship-series match-up between the Mavericks and the Miami Heat.

The NBA is the first of the major sports organizations to offer such a service, though other leagues are reportedly converting game footage into digital clips in order to satiate fan demand. An executive with Major League Baseball reveals the league's plans to introduce a video-search product later this year, allowing fans to search through hundreds of clips to find specific highlights (which will likely be available for free). The National Football League is introducing a video-heavy version of its web site this summer and exploring the ramifications of offering historical video footage.

Billionaire entrepreneur Mark Cuban is best known as the eccentric owner of the Dallas Mavericks, an NBA team. But he got his start as an entrepreneur at the age of twelve, selling garbage bags. His other early money-making efforts included providing disco dancing lessons and a chain letter that earned him more than $1,000. The foundation of his fortune, though, came about through starting and selling technology companies. Unlike so many others in that field, Cuban managed to avoid the dot-com bust by diversifying his portfolio. He's now one of the world's 500 richest people, according to Forbes.

Cuban is a confessed admirer of Ayn Rand, particularly a fan of her novel, The Fountainhead, and also of objectivist philosophy; he leans toward the libertarian end of the political spectrum, though he doesn't get much involved in politics. A casual man, Cuban rarely wears a suit and never wears a watch. He purchased his stake in the Dallas Mavericks from H. Ross Perot in 2000, and has since been a very visible and outspoken supporter of the team, often appearing at games in a Mavericks jersey. He's been fined a number of times by the NBA for criticism of referees and league officials, though he matches his fines with donations to charity. In one notable incident, Cuban's complaint that a league manager wasn't smart enough to run a Dairy Queen eventually resulted in Cuban working the counter at a Dairy Queen in Texas, where delighted fans lined up around the block to be served by him.

Other widely reported incidents include a 2003 scuffle with professional wrestlers Eric Bischoff and Randy Orton, which turned out to be a scripted stunt. In 2006, when film director M. Night Shyamalan expressed concern over the marketing experiment of simultaneously releasing Steven Soderbergh's film Bubble in theaters and on DVD, Cuban called Shyamalan an "idiot."

Makes one wonder who Mr. Shyamalan might vote for as the Most Annoying Money Expert of 2006.
