Completing this week’s holiday shopping tips trilogy is the ZDNet Holiday Gift Guide 2020. Another reputable product review website, ZDNet began as a subscription-based digital service called “ZiffNet” that offered computing information to users of CompuServe. (Some will recall that first version of OBA-NET was also hosted on CompuServe.) It has a long online history, spanning most of the major online services and is now a part of C|Net and CBS. According to Wikipedia, ZDNet currently operates a network of about 50 blogs loosely aligned by its major verticals: companies, hardware, software, mobile, security and IT research.
