In America and Europe magazine publishers have a common headache: total circulation is either flat or declining slightly as people devote more time to the internet, and an ever greater share of advertising spending is going online. Magazine units are mostly a drag on growth for their parents. Time Inc, the world’ s biggest magazine company, has to fend off rum ours that its parent, Time Warner, will sell it. People in the industry expect that Time Warner will soon sell IPC Media, its British magazine subsidiary. The business model for consumer magazines is under pressure from several directions at once, both online and off. Magazines have become more expensive to launch, and the cost of attracting and keeping new subscribers has risen. In America newsstand sales have been worryingly weak, partly because supermarkets dominate distribution and shelf-space is in short supply. The internet’s popularity has hit men’s titles the hardest. FHM, the flagship "lads" magazine of Emap—a British media firm, for instance, lost a quarter of its circulation in the year to June. Not long ago consumer magazines were Emap’s prize asset, but slowing growth from the division contributed to the company’s decision to put itself up for sale. Men’s magazines are in trouble in most developed-world markets as people have quickly switched from magazines to online services. There are good reasons why magazine owners should not feel pessimistic, however. For readers, many of the pleasing characteristics of magazines—their portability and glossiness, for instance— cannot be matched online. And magazines are not losing younger readers in the way that newspapers are. According to a study by the digital arm of Ogilvy Group, appetite for magazines is largely unchanged between older "baby boomers" and young "millennials". On the advertising side, magazines are faring much better than newspapers, which are losing big chunks of revenue as classified advertising shifts online. Advertisers like the fact that in many genres, such as fashion, readers accept and value magazine ads and even consider them part of the product. Unfortunately, magazine publishers have been slow to get onto the internet. "Eighteen months ago the internet was something they worried about after 4pm on Friday," says Peter Kreisky, a consultant to the media industry, "but now it’s at the heart of their business model. " To their credit, however, big magazine firms are doing far more than reproducing their print products online. They offer people useful, fun services online—Lagardere’ s Car and Driver website, for instance, offers virtual test drives, and Better Homes and Gardens online has a 3D planning tool to help people redesign their homes. Which of the following is true of magazines’ current situation

"Frontier", one of many English words that took on new meanings in North America, has assumed as well a role in explaining the continent’s history during the past five hundred years. In time the word has acquired other connotations, both positive and negative. Among historians, the term "frontier" is most closely associated with Frederick Jackson Turner, whose essay profoundly influenced American historiography for forty years after its publication in 1893. Reacting against historians who considered American history essentially an outgrowth of British and European institutions, Turner argued that Old World customs and attitudes broke down and reformed in America’s radically different physical and social environment. The opportunity of "free land" drew pioneers westward into settings that required them to modify or scrap entirely many of the institutions and values of their previous lives. The result was a "merged nationality", a distinctive culture and people. Although he emphasized the positive, Turner observed that the same conditions that had helped reshape the society had less desirable effects. For instance, as early governments they had to create political forms almost on the fly, they were less likely to innovate than to copy what they knew from the past. The tension between change and tradition was played out in gender relations. Frontier conditions often required women to take on roles usually reserved for men, but the crushing load of work made women’s lives difficult and dangerous and left little room for individual fulfillment outside their labors. By Turner’s death in 1932, more fundamental critiques of his ideas were being heard. Some stressed that many other factors—among them patterns of immigration, American society’s middleclass nature, etc.—influenced the national character at least as much as the frontier. Others argued that class divisions and social and economic hierarchies have been much more a part of American life than the frontier-inspired equality implied in Turner’s work. The effect of these various critiques has been paradoxical. No longer considered the primary formative force on continental history, the frontier has been more broadly defined and its explanatory power has grown. Recent research has explored the interactions among Europeans, Euro-Americans, and Indian peoples. Along the various frontiers there developed what the historian Richard White has called a "middle ground", cultures of overlapping customs and mutual borrowing in which all sides created new terms of understanding and exchange. Consequently, many tribes merged and consolidated to meet the threats and opportunities posed by the newcomers. A frontier in this sense was certainly not a division between "civilization and savagery", but rather a place where peoples, ideas, cultures, and institutions came together and interacted on many levels, sometimes mixing and sometimes conflicting but always in mutual influence. Frederick Jackson Turner is mentioned to______.
