Growth of Internet hosts and active domains (neurons, for argument's sake) since the 1990's. Expansion has been steady with surprisingly little impact from economics, the dow jones, or level of venture capital funding. One would expect a dramatic plummet in 2001 and 2002, perk up, and drop again. But this is not the case. What is seen is a temporary pause in an inexorable expansion - that's probably still in the early days, looking at the accelerating pace of growth in host names - including the fastest-ever growth between November 2008 and February 2009, according to this sample.
