As Twitter evolves we are seeing a definite minority skew for the medium, with African-Americans, Latinos and Asian-Americans accounting for 41% of total users versus 34% for Facebook and 33% for total Internet users.
While the company is focusing on growing its Latino audience, its current sweet spot is young African Americans. 40% of African-American Internet users between the ages of 18-29 use Twitter compared with 28% of Whites in that age group. (Koh, 2014)
Advertisers that have taken notice and are doing something about it include AllState, Home Depot and "12 Years A Slave." I imagine that others will soon follow.
