Starting Monday, video screens in coffee shops, casual eateries and airport newsstands in five major cities will display the work of The New York Times, under a deal with RMG Networks, a major owner of such screens. RMG will take some 850 screens it operates in the main business districts of New York, Los Angeles, Chicago, San Francisco and Boston and rebrand them as the NYTimes.com Today network, displaying only material taken from The Times’s Web site, interspersed with ads. Another 850 screens will be added over the next few months, and some of them may be in other cities. The basic presentation will show an article on the left side of the screen and pictures and video on the right, on a 14-minute cycle, with ads, and some of the content, tailored to the location. Viewers can use cellphones to download either the Times work they have seen or coupons from the businesses they are visiting. Yasmin Namini, The Times’s senior vice president for circulation and marketing, called the arrangement with RMG “a good branding opportunity for NYTimes.com,” exposing it to new readers in important markets. The screens are an appealing vehicle for advertisers, “especially in areas where people are waiting, sitting, standing in line, kind of captive for a while,” said Linda Kaplan Thaler, chief executive of the Kaplan Thaler Group, a Manhattan-based ad agency. RMG is one of several companies, like Health Club Media Networks and Clear Channel, in the fast-growing business of placing video screens in front of affluent, captive audiences.
