There are no pioneers for Kim. No one doing what she's doing (she blew Paris out of the water).
Talentless or whatever you wanna say she is: Cover of FORBES, private meeting with the PRESIDENT, TIME Most Influential. Praised in tech community (see: speaking at tech conferences, on the cover of apps) for her apps (which Britney copied and failed miserably). She's more famous than Britney EVER was.
Meanwhile, over in pop, Britney has been eclipsed and stomped on by her peers (Justin Timberlake and Beyonce, even Xtina found a niche). They tried to make her out to be the next Madonna and she crashed, six years in. She lost. She's over. Get over it.
Kim won. Britney lost (she loses against pretty much everyone, but especially Kim).
