Variety: Byron Allen’s National Association of African-American Owned Media has accused Comcast of violating key terms of its agreement with the FCC that paved the way for its 2011 acquisition of NBCUniversal. The org filed a petition with the FCC late Friday outlining its assertion that Comcast has not complied with its promise to launch multiple new cable channels owned at least in part by African-Americans within eight years of the merger.
