The Rev. Jesse Jackson plans to lead a delegation to the Hewlett-Packard annual shareholders meeting on Wednesday to bring attention to Silicon Valley's poor record of including blacks and Latinos in hiring, board appointments and startup funding. Jackson's strategy borrows from the traditional civil rights era playbook of shaming companies to prod them into transformation. [...] he is bringing it to the age of social media and a booming tech industry known for its disruptive innovation. Earl "Butch" Graves Jr., president and CEO of Black Enterprise magazine, says Jackson is shining a light on the fact that technology companies don't come close to hiring or spending what is commensurate with the demographics of their customers. "While we certainly agree that diversity is an important issue in corporate America, we're puzzled by Rev. Jackson's sudden interest in HP," said HP executive vice president Henry Gomez in a statement emailed to The Associated Press. Gomez also points out that in 2013, HP spent nearly $1 billion with almost 500 minority business enterprises in the U.S. and an additional $500 million with businesses owned by women. Microsoft named John Thompson, an African-American, as chairman of its board last month after he led a search that culminated in the appointment of Satya Nadella as the software maker's new CEO. Another African-American, Denise Young-Smith, runs Apple's human resources department, which oversees the personnel policies governing the iPhone maker's nearly 85,000 employees and contractors. She reports directly to Apple CEO Tim Cook. [...] Google's chief legal officer, David Drummond is an African-American who has been one of the company's top executives for the past 12 years.
