Just good business; blacks are among the few remaining segments of the population hooked on TV and movie screens. Marketers love them; they let them continue operating with a 1990s model instead of having to move with technology...
A guy who manages one of the local businesses made a similar observation to me one day, telling me that if it weren't for the influx of urban blacks, he'd be left to rely on the very elderly...who count their pennies.

As a total percent of their income, blacks spend more money on movies than do white people.
Really, they spend a higher percent of their incomes on just about every single entertainment form.
