Very thought provoking question for me but google searches haven't taken me far. I would greatly appreciate any pointers and thoughts
What I have so far from my understanding of the question:
#blacklivesmatter - clearly promotes black power through protests, twitter, and other forms of social media
Beyoncé - promotes black lives though performances, songs, videos
Kendrick Lamar - advocates awareness through performances, songs, videos
United Nations Working Group of Experts On People of African Descent - created The International Decade for People of African Descent to
I'd love to discuss this, but perhaps you could elaborate on your question more. Food for thought: Black Power (our traditional notion of the phrase, stemming from Stokeley Carmichael's 1966 iteration) links black culture and politics, using media to promote an alternate vision of what it means to be black and in America (note: not necessarily a "black American" or "African American", because some, like Carmichael, were not American-born). So, from James Brown's 1968 "I'm Black and I'm Proud" to the 70s black afro & "Blaxploitation" films to emergence of hip hop and rap in the 90s to Beyonce's Super Bowl Half-Time show, Black Power ideology has always had an influence on American media and culture.
