MSNBC announced today that it has officially handed its 6 p.m. weekday slot to the Rev. Al Sharpton. His show, called “PoliticsNation,” begins Aug. 29 and will feature discussions about major news stories. Reports of Sharpton’s possible hiring at MSNBC stirred some controversy. Some suggested it could create a conflict of interest, given that he lobbied the FCC to approve the Comcast-NBC Universal deal last year. Black journalists also criticized the move, saying MSNBC is one of many cable networks that has hired black people based on their celebrity status rather than their journalistic skills.
