(A) Cumulative number of publications on the diffusion of innovations, excerpted from Ref. [9]. The curve is obtained by fitting a functional form [see Eq. (12)] to the data points where is the saturation number at . The fitting parameters are . (B) The same data shows larger deviations when fitted with the logistic function (green) or the error function (blue). Their best fitting parameters are and , respectively. (C) Broadband penetration rates in Greece and the United Kingdom (UK) from Eurostat [22]. The curves were obtained in the same way as above with Eq. (12), yielding for Greece and for the UK.
