Stefano Tonchi, W’s editor in chief for the past two years, is ringing in the magazine’s 40th anniversary with a promotional blitzkrieg. The 30th birthday was celebrated too, but 10 years later, W has a new ad-thick November issue and a newly redesigned iPad app. The centerpiece of the rollout is a new glossy coffee-table anthology that looks back at W’s history from the days it was a biweekly broadsheet.
