The Null Device
At the turn of the 1930s, recorded music was seen as an existential threat. Films with sound started appearing, and their prerecorded musical soundtracks started threatening the livelihoods of the musicians who, until then, had played accompaniments to silent films in cinemas. To wit, the American Federation of Musicians launched a campaign against the tyranny of “canned music”, which their advertisements depicted as a malevolent robot:
The campaign was ultimately unsuccessful, though recorded music was seen as a threat to live musicians for decades after that. In the 1950s, for example, when the BBC was establishing a studio for experimental electronic music, it dubbed the studio with the decidedly unmusical name of the Radiophonic Workshop, perpetuating the fiction that its function only peripherally touched on the kingdom of music, as to avoid antagonising the unions of the musicians who worked on other BBC broadcasts.
Some good news for people (well, Britons mostly) who like good design. You may remember Min-Kyu Choi's prototype of a folding electric mains plug compatible with both Britain's ruggedly oversized power sockets and its conservative electrical safety standards, which briefly made the news back in 2009:
Well, after some two and a half years, Choi's design (with some modifications) is finally making it onto the market, at least for certain values of "making it" and "market". Known as The Mu, the plug will be available as a folding USB charger, which will be sold for £25 at the Design Museum in London (i.e., this is currently for design enthusiasts only). As for being able to charge your ultra-light laptop with a plug that doesn't look anachronistic next to it, that's still some way off.
