We do see it differently. People who demonstrate to call attention to their grievance, depend on the media to spread the word. The media becomes the instrument of protesters seeking a broad audience for the dramatizing of their cause. So it is used as much as it uses. And, how do you think you know about black people doing good things if this wasn't reported in the media? The good work doesn't make headlines because accomplishing things is not an agitation. These achievements, however, may very well be the final stage of a movement that began with drastic measures of public protest!
Celebrities and the causes they embrace command attention because the public is riveted by what famous folks do, and when what they do benefits a worthy cause, then how bad can this be? Martin Luther King's March on Washington was a massive gesture of protest that was saturated with celebrities. Media from all over the world covered this dramatic event, which was what its organizers hoped for. Without extensive media coverage, the desired impact would not have been made.
To this day, the march on Washington still generates news because hearing about it is what the people want, and the media gives people what they want. The masses leading their day-to-day, humdrum lives, would rather hear about the humanitarian activities of celebs than when the Salvation Army will be picking up old articles for resale in their outlets.
