Celebrities call for 'Black Friday' boycott

US celebrities called for a boycott to take place Friday -- one of the busiest US shopping days -- to protest a grand jury's decision not to prosecute a police officer who fatally shot a black teen.
      
A number of well-known figures, among them hip-hop mogul Russell Simmons, have signed onto the action, under the Twitter hashtags #NotOneDime and #BlackoutBlackFriday.
