African-Americans on average watch the NBA 62.9% more than they did in 2003-04. Asian-American viewership jumped up 57.1% since 2010-11. Hispanic's and Whites have seen increases of 14.4% and 13.7% respectively. The NBA has one of the most culturally diverse following in sports, as well as the youngest with 43% of fans under the age of 35.

It's actually very interesting to see how much Asian-American viewership has jumped between 2010-11 and 2013-14. While the chart makes the jump in African-American viewership seem most significant, the increase took place over a ten year span compared to just a 3-year span for the Asian-American audience. Overall, the chart does a good job of showing a growing diversity of viewership. Has this occurred in other sport viewership, or just in basketball?

Great question. I don't have the data, but the NBA is much more popular in China than baseball or football. Part of the jump in recent seasons can be attributed to Jeremy Lin if you remember "Linsanity" a couple years ago. If we have another star from China play in the NBA similar to Yao Ming, viewership would skyrocket. In Japan basketball isn't popular, but baseball is huge!
