A colleague pointed me to an interesting website for the International Telecommunications Union. The ITU is an organization that collects and disseminates telecommunications data. Their website provides information on various topics and also includes access to graphics and free data. On the right side of their main page there is a list of datasets about communication systems by country for years 2000-2010. This is a very nice set of data because the data are time-series, and because the data appear to have few missing values. For this post I downloaded the dataset "Percentage of Individuals using the Internet".
