As Mark Poster points out, technologies of the second media differentiate themselves from the first media age. Whereas the first media age was defined as having few producers disseminating to a large number of consumers, the second media age is defined as having multiple producers and consumers. The obvious example of the second media age in practice, with multiple producers and consumers, is the Internet. I mention this because of the recent events in Burma and the important role of media technology.
One of the crucial struggles, apart from the protests, is the dissemination of information, pictures, and videos. It is through these that the people of Burma can hope to provide 'real time' coverage of what is occurring. While it is estimated that under 1% of Burma's population have access to the Internet, which is also censored, the cyber-bloggers of Burma have been able to exploit loopholes. The BBC website has an article on this practice here.
However, the Burma Junta have realised that the flow of information reaching the outside world is going to be a problem, and I recently heard they are closing down Internet cafes. The other problem, as Mark Poster discusses in his recent book, is that the Internet is not immaterial, and a lot of material technology is required for access to the WWW (phonelines, mobiles, PCs...).
It was even report on the 18th September that the Junta cut off mobile phone service to foreign reporters, which can be read here.
At present, I don't have much to say, but only wanted to bring attention to the significance of the medium in Burma, which I will certainly be paying attention to find how it plays out.
