Tech Advisor

Tech Advisor's 25-year legacy began in August 1995 when IDG launched PC Advisor magazine. The website followed in 1996, and in June 2017 it was rebranded as Tech Advisor. Tech Advisor still covers all types of personal computers, but its coverage has expanded to new and emerging tech verticals: from wearable tech and smart home products to streaming services, entertainment, gaming and other cool new gadgets and accessories. Tech Advisor attracts buyers of all experience levels across the whole range of consumer technology - and now caters to small- and micro-businesses, too. With strong ties to all the major manufacturers, as well as incredible product knowledge built from years covering the consumer tech industry, Tech Advisor is uniquely positioned to tell users and influencers what to buy, and how to get more from their purchases.
