These are tough times for high-tech magazines. Popular ones such as Yahoo! Internet Life, The Industry Standard, On Magazine, Red Herring and Upside recently closed down, and other established ones like Wired and Business 2.0 have struggled. So it takes a lot of guts to launch a new technology magazine — and Fred Davis, the former editor of PC Week and PC Magazine, has guts. He’s launched a new magazine, DigiT, aimed at the consumer masses. It’s meant to be a “digital lifestyle” magazine, with features such as Dean Kamen’s Segway Killed My Puppy! The pilot issue is on the newstands now. With its consumer approach and its timing — as the ad market slowly picks up — it might just succeed, if it’s smart and avoids the excesses of the dot-com era failures.
