Hi everyone, #1 DVD is diffusing faster than the Internet, as is the mobile phone in many places. It is not unprecedented. Furthermore, the diffusion curve here suggests that television might have been as steep. #2 Everett Roger's book "Diffusion of Innovations" is highly recommended. I haven't read the fifth edition so I cannot speak to it, but the fourth is really great. #3 Internet diffusion should be probably broken down by dail-up vs high-speed and definately by country. #4 It shold also be noted that this chart wold sugest the internet was invented 9 years ago. Would that make the chart 2000, and the internet being correlated with WWW? One should be very careful to make such claims, given that the role of DARPAnet and all sorts of precommercial work has been embedded in the history of the Internet's development. It would still behave like a logarithmic curve but it does inject a different sort of ideology into the picture about who is responsible for the Internet's diffusion, AOL, the FCC or general diffusion trends. #5 There is some evidence to suggest that the Internet will not receive the total diffusion that telelvision did. It is already being outpaced by mobile phones in many places. Nonetheless, this is still an interesting graphic. Thanks!
