Primedia joins the growing group of publishers hoping to grab a piece of the homeland security pie, launching Transportation Security Magazine, a spin-off of its Access Control & Security Systems Magazine. The pub, whose first issue became available last month, is scheduled to publish twice in 2003 and will be produced by the editorial staff of Access Control & Security Systems. The pub focuses on news and information surrounding the development and implementation of security technologies at airports around the country.
