Hi All, I haven't been following the timeline conversation so I don't know the particular motivations behind it, but it seems rather short scale to my mind. For instance, if one wants to understand the history of digital audio, you've got to at least go back to Fourier, who was interested in heat but whose waveform analysis made digital audio possible. And if you want to talk about the relationship between music and number, well now we're back to Aristotle and Aristoxenus. If we're interested in keyboard instruments, the history of typewriters seems important, and if we're interested in the history of databases the census, the postal system and the invention of tabulation machines seems important. Also the 20th century dates seem off to me. 1950s is an important period for the diffusion of television in the US but much of the key policy and technological development happened between the 20s and 40s. One might also look internationally to German deployments of television and so forth. Again, I don't know the motivation behind such a timeline but if it is meant as a guide to media history relevant to people who are interested in digital media today, I would recommend more attention the extant media historical scholarship. Best, --J
