I stumbled across this great video put together for a lecture at AIGA Baltimore last month. Titled 'The State of the Internet' by JESS3 (on Vimeo) it features some startling numbers about all of us internet users.
One section I find especially interesting begins about 2 minutes in when online video statistics are provided, then at about 2'50" when the launch date of major social network sites are listed. In that section, it's interesting to look at the last couple of years...it's about the same as the first couple of years listed! So enough talk...take a looK:
