Gabriel Tarde undertook the first study of diffusion as a social process

The French sociologist Gabriel Tarde first studied how new practices spread through societies, alongside German and Austrian anthropologists and geographers such as Friedrich Ratzel and Leo Frobenius. This established diffusion as a subject of academic enquiry, laying the intellectual groundwork for later work on how technologies are taken up across populations.

Ryan and Gross published the Iowa hybrid corn seed adoption study, defining adoption as a process

Their study of hybrid corn seed adoption in Iowa consolidated earlier diffusion work into a distinct research paradigm that was cited consistently thereafter. It first identified adoption as a staged process and introduced the connectedness of a potential adopter to the wider community as an element of diffusion.
