Yesterday, we started hearing rumors of big layoffs on the way at Niche Media, that stable of glossy, journalism-free socialite-focused city magazines across the country. Today the Philly Daily News confirmed that Philadelphia Style had "much of its editorial and creative staff" laid off yesterday. But that may have been just the beginning; another tipster tells us that there are "massive layoffs" across the company, and "people are getting fired with no notice from editorial on a lot of different magazines — Hamptons, Boston Common, Philadelphia Style, LA Confidential..." Is Niche CEO Jason Binn's company the latest entrant in the Great Magazine Die-Off? If you have more specifics on the cuts, email us. [We're also hearing that the rumored looming layoffs at Viacom could actually be coming next week—stay tuned.]
