Watch any TV news roundtable with Newsweek International editor Fareed Zakaria and you can be sure the discussion will have some nutritious calories. Now Zakaria has got his own roundtable. Starting June 1 at 1 p.m. ET on CNN, he'll host Fareed Zakaria - GPS, a weekly hour devoted to international affairs (the initials stand for global public square). Each Sunday, the show will include a 25-minute interview with an important world player (former British Prime Minister Tony Blair is the first guest). Zakaria recently shared his global wisdom with The Biz.
