Great site and interview. The amount of work Colin had to put in on his own to get the magazine published then survive, seems to parallel the work Dave does to keep the eevblog alive too; its mostly a one man shop. Colin reach only 14,000+ people monthly, and lasted ~ 15 issues, then there was the cash out lay, the mailing etc., such a contrast on how the Internet magnifies and simplified publishing.
In the US, Electronics was dominated by Gernsback Publishing, via Radio Electronics and cousins, and Popular Electronics, from Ziff Davis group [ who later started PCMag and others]. However, with the rise of the PC in the late 1970s, marked the slow decline and death of most electronics mags. Likewise, the rise of the Internet led to the decline of PCMag, Computer Shopper and most notably BYTE. They exists now as online versions, but they are a shadow of their former selves.
