Touch Arcade: Why do some games briefly spike into the top charts and some say awhile?

Touch Arcade iPhone, iPad, and iPod Touch Games

Why do some games briefly spike into the top charts and some say awhile? Jul 31st 2013, 00:24, by flathead I understand continual advertising/promotion can help bolster games to stay in the top charts but are the organic downloads alone from being in the top charts not enough? I see some apps spike in the charts, top 10 free, but they only stay a few days and then fall back into oblivion. Why do they fall so fast if they are receiving (I assume) so many organic installs from being on the top of the charts?
