1. Introduction
NBA is the abbreviation of U.S. National Basketball Association, the richest one in four professional sports organization-baseball, rugby union, ice hockey and basketball association with more than 4 billion dollars annual income. NBA is the most globalized and influential professional sports organization in the world, lively broadcasting events to 212 countries with 42 languages. What’s more, as a successful case, NBA often appears in marketing materials in business colleges. They learn about how NBA markets league matches through the NBA star brand effect and modern media and how NBA steps to globalization by means of international strategy. In the end of 2005, Forbes made a special report of NBA: The Business of Basketball. In the detailed report of its running condition, the average value of 30 teams in NBA achieved 326 million dollars with an average increase rate of 9%.

3. Conclusion
As a purely commercial competition, NBA can only enhance its quality to achieve high profits. Only high-quality products can realize high returns as well as high-quality ornamental value. Thereby, increasing the view value of NBA game is the most concern for NBA. What’s more, NBA is trying to launch commercial development rules to continuously improve the ornamental value of the game and achieve the desired commercial value. (Ji Guangxing, Chen Ping 2011)

But the pursuit has been considered inherently separate from seismology as we normally think of it; the slippage of ice sheets and that of slabs of the Earth’s crust arise from different causes, follow different dynamics and, for those who go to the trouble to listen, make different sounds. While a large earthquake can trigger tremors in distant, tectonically active regions, earthquakes and icequakes have been considered unconnected events. But this week saw the publication, in a paper in Nature Geoscience, of the first evidence linking the two.
Zhigang Peng, a seismologist at the Georgia Institute of Technology in America, and colleagues noticed that glacial calving—the falling of large chunks of ice from the end of a glacier into the sea—can be triggered by earthquakes that originate thousands of kilometres away. The tsunamis created by such quakes tug on icesheets, inciting ruptures and fractures.
But Dr Peng wondered whether remote earthquakes could trigger icequakes farther inland in Antarctica. To be sure, seismic activity is not uncommon in Antarctica; ice formation, too, triggers icequakes of smaller intensity. But the team was looking for something more substantial. They chose to examine data around the time of the 2010 earthquake in Chile—among the strongest on record, and not too distant from Antarctica. They suspected that only so-called surface waves, which travel along the Earth’s surface rather than through its bulk, could trigger icequakes. Such waves travel at a known speed and have characteristic frequencies, so the team knew what to look for and when.
On analysing the data from 42 Antarctic seismographs, they found 12 clear signals that marked the occurrence of icequakes within six hours of the Chilean quake, leaving little doubt as to the cause. Relatively speaking, the icequakes were minuscule. But as Kate Allstadt, an icequake specialist at the University of Washington, puts it, “things we think of as strong, like glaciers, can still react to them if the conditions are right'. Dr Allstadt has found that the annual load of snow on Washington’s Mt Ranier is enough to trigger thousands of icequakes each year.
Understanding these delicate mechanisms as they play out in Antarctica is critical because the vast majority of the planet's ice is trapped there. The movement and eventual loss of glaciers at the Earth’s poles will have a tremendous global impact; the collapse of the Western Antarctic Ice Sheet, which has arguably
