Twitter employs only 49 African Americans despite diversity pledges

Rev Jesse Jackson says black people are becoming 'intolerant' with companies like Twitter, which has exploited its large base of minority users for ad revenue

Twitter employs just 49 black people out of a total US workforce of 2,910. The tiny number of African American staff - 35 men and 14 women - represents just 1.7% of Twitter's US staff.

The Rev Jesse Jackson, president of the Rainbow/Push Coalition, who has long campaigned for tech companies to be more transparent about their lack of minority employees, told the Guardian that black people are "becoming intolerant" of Facebook and other Silicon Valley companies' lack of progress in making their offices more diverse.
