We then test this on the time-evolution of the Gentoo package dependency graph. We find that the Bass model of innovation diffusion fits the growth of the number of packages depending on a given library. Interestingly, we also find that low-level packages have a primarily imitation driven adoption and multimedia libraries have primarily innovation driven growth. %B Proceedings of the 11th Working Conference on Mining Software Repositories %S MSR 2014 %I ACM %C New York, NY, USA %P 316–319 %@ 978-1-4503-2863-0 %U http://doi.acm.org/10.1145/2597073.2597079 %R 10.1145/2597073.2597079 %> https://flosshub.org/sites/flosshub.org/files/bloeman.pdf
