new technologies: diffusion comparison diagram
Hello, Can someone point me to a downloadable diagram that compares diffusion rates for new technologies, e.g. telephone, VCR, internet etc? I've seen many versions of this sort of diagram, but can't seem to locate one that I can put directly into a powerpoint presentation. It doesn't really matter whether the data is North American or from elsewhere, it's the overall trendlines I'm interested in. Any suggestions as to where to find something like this would be most appreciated. Thanks, catherine middleton cmiddlet@ryerson.ca

This is somewhat surprising. You intend to convey a picture that all over the world the diffusion of household technologies went the same way, the same speed? Where did you get a source for that? It would be an interesting point whether this was the case. Regards, Frank -- ...................... Dr. Frank Thomas FTR Internet Research Rosny, France

I recollect one of the papers I reviewed for Telecoms Policy looked at diffusion, but not sure if comparative rates were used. I also remember an economics paper at TPRC, where adoption rates of different consumer devices (not quite new technologies, certainly not since the invention and application of the semi conductor / integrated circuits)) from the basic telephone onwards. Naturally I don't have anything to hand - but you might be able to locate these.

search for "Bass curves". i'd look in my copy of Rogers "diffusion of innovations", but its at home. your library probably has it too. not sure that searching for Bass curve stuff will get you a useful diagram, but it at least gets you into the right region of theoretical discourse. elijah
I think you may be looking for something like this: http://alex.halavais.net/research/rate.png Sorry for the quality, and lack of citation (I don't know where I got it). I know there are better images out there--I've used them--but I can't lay my hands on one at the moment. Alex Halavais Quoting catherine middleton <cmiddlet@ryerson.ca>:

Alex provides this graphic re technology diffusion rates:
I find it curious that they attribute the "start" of the Internet to 1991. One of the Internet time lines suggest that 1990 was when dialup service was first commercially available (see http://www.zakon.org/robert/internet/timeline/), so perhaps that's the rationale? I'm not familiar enough with these other diffusions to know for sure, but it seems iffy that the others had the same kind of non-commercial incubation that the Internet did, so a straight comparison may be misleading.

the rationale is probably that it became legal to route commercial traffic over the mainstream internet at around that date. ;)

right - most of those things had commercial sponsors pushing them along. i just did a little googling and found this paper, specifically relating diffusion of innovations methods to the early internet's development: http://www.au.af.mil/au/awc/awcgate/innovation/adoptiondiffusion.htm elijah
Dear AIR'ers - Ok, I think possibly this could be very similar to the "early adopter" curve that went around in the management circles in the 1980's. It is not technology specific. It states that the first 10% of adopters arrive 'early' to the technology, 70% arrive in the middle of the life of the technological innovation, 10% arrive at the end, 10% never get there, it looks something like a normal curve with 5% left in each tail. One paper that uses this adoption pattern (but hardly a communication type reference): Muth, R. M. and J. C. Hendee (1980). "Technology transfer and human behavior." Journal of Forestry: 141-144. The question then is to differentiate as to what are the appropriate timeframes for each technology, but of course, one could be fairly early to internet (1985) and not arrive at all with SMS (oh well). As far as internet in 1991, ok, that leaves out all the unix hackers. Oh well again. Cheers, Denise ===== "The distance between here and there is growing; and getting even larger as we speak" (S. S.
