In this new Pulse focus area, we’ll track the extent to which core Internet services are distributed or concentrated among a few actors. Based on measurements of top websites and including analysis of seven technology markets we will soon present two metrics of Internet centralization tracked over time.
We’ll be looking at the distribution of market shares in the provisioning of core technologies to infer the degree to which power is concentrated or distributed, and how this is changing over time. To this end, we compute two metrics based on the underlying data of market shares – the Gini coefficient and the Herfindahl-Hirschman Index (HHI) – that each provide similar, yet different, angles for understanding trends of Internet centralization.
