Technology Review relaunched: infotech, biotech, nanotech, and biztech

Technology Review has recently relaunched its website, and reduced the print magazine from one issue per month to one issue every other month. According to its editor, Technology Review has done what many publishers yearn to do, but dare not: it has turned its business upside down. Technology Review has been a print magazine with a website; from now on, it will be an electronic publisher that also prints a magazine.

Owned by MIT, Technological Review has been reporting emerging technologies and analyzing their likely impact since 1899. The Magazine now has four channels: infotech, biotech, nanotech, and biztech.
