@ rihanna forever...

britney does not do self promotion (more than likely too stressful). however, most of the media and radio stations get behind her with ginormous super hype never showered on an artist without them making a personal appearance.

christina promoted her 'bionic' cd and movie 'burlesque' on almost every media form in existence and as soon as she stopped so did any press mention of her or her projects.

not only does britney have the media and music industry checking big for her, but she has fans (some wildly obsessed ) campaigning over the top for her. there's blog sites where fans encourage each other to buy multiple copies of her cds, call radio stations, repeatedly , tweet her and her producers concerning her releases. one site even stated fans were tweeting president obama (were they kidding...don't know).

with the media, the music industry and ravenous her fans at her back , she's getting all the promotion any celeb would ever need.
