判断题Until the late 1940s, when television began finding its way into American homes, companies relied mainly on print and radio to promote their products and services. The advent of television brought about a revolution in promoting products and services. Between 1949 and 1951, advertising on television grew 960 percent. Today the Internet is once again transforming promotion. By going online, companies can communicate instantly and directly with prospective customers. Promotion on the World Wide Web includes advertising, sponsorships and sales promotions like contests and coupons. In 1996, World Wide Web advertising revenues reached $300 million. Effective online marketers do not merely transfer hard-copy ads to cyberspace. Successful sites blend promotional and non-promotional information, indirectly delivering the advertising messages. To encourage visitors to their sites and to create and cultivate customers" loyalty, companies change information frequently and provide many opportunities for interaction. One of the best online promotion web sites is the Ragu Web site. Here visitors can find thirty six pasta recipes, take Italian lessons, and view an Italian film festival. But they will find no traditional ads. So subtle is the mix of product and promotion that visitors hardly know an advertising message has been delivered. Sega of America, maker of computer games and hardware, uses its Web site for a variety of different promotions, such as introducing new game characters to the public and supplying Web surfers the opportunity to download games. Sega"s home page averages 250,000 visitors a day. To heighten interest in the site, Sega bought an advertising banner on Netscape, thereby increasing site visits by 15 percent. Online participants in Quaker Oats" Gatorade promotion received a free T-shirt in exchange for answering a few questions. Quaker Oats reports that the online promotion created product loyalty and helped the company know its customers better. Now, to target specific Internet users, an increasing number of companies are using "push" technology which automatically delivers customized news and other information to users" computers when they log onto the Internet. Although organizations like Nielsen Media Research are developing technologies to enhance audience measurement and tracking, it remains difficult to assess how many times the same person looks at an ad and who that person is. Although online promotions can be glamorous and sophisticated, they are not perfect. For a well-designed marketing mix, industry experts advise companies to use the Internet as a supplement to other advertising media.

判断题There are some unique problems in international trade and companies doing business overseas must be aware of them. In particular, these include (a) cultural problems, (b) monetary conversion, and (c) trade barriers. When companies do business overseas, they come in contact with people from different cultures. These individuals often speak a different language and have their own particular custom and manners. These differences can create problems. For example, in France, business meetings begin promptly at the designated time and everyone is expected to be there. Foreign business people who are late are often left outside to cool their heels as a means of letting them know the importance of promptness. Unless one is aware of such expected behaviors he may end up insulting the people with whom he hopes to establish trade relations. A second traditional problem is that of monetary conversion. For example, if a transaction is conducted with Russia, payment may be made in rubles. Of course, this currency is of little value to the American firm. It is, therefore, necessary to convert the foreign currency to American dollars. How much are these Russian rubles worth in terms of dollars? This conversion rate is determined by every market, where the currencies of countries are bought and sold. Thus there is an established rate, although it will often fluctuate from day to day. For example, the ruble may be worth $0.75 on Monday and $0.72 on Tuesday because of all announced wheat shortage in Russia. In addition, there is the dilemma associated with converting at $0.72. Some financial institutions may be unwilling to pay this price, feeling that the ruble will sink much lower over the next week. As a result, conversion may finally come at $0.69. These "losses" must be accepted by the company as one of the costs of doing business overseas. A third unique problem is trade barriers. For one reason or another, all countries impose trade barriers on certain goods crossing their borders. Some trade barriers are directly related to exports. For example, the United States permits strategic military material to be shipped abroad only after government permission has been obtained. Most trade barriers, however, are designed to restrict imports. Two of the most common import barriers are quotas and tariffs. A quota is a quantitative restriction that is expressed in terms of either physical quantity or value. For example, a quota that states that no more than 50000 Class A widgets may be imported from Europe each year is a restriction stated in terms of physical quantity. Meanwhile, a quota that restricts the importation of a certain type of Japanese glassware to no more than $1 million worth a year is stated in terms of value. A tariff is a duty or fee levied on goods being imported into the country. These tariffs can be of two types: revenue or protective. A revenue tariff is designed to raise money for the government. These tariffs are usually low, often amounting to less than twenty-five cents per item or pound. A protective tariff is designed to discourage foreign businesses from shipping certain goods into the country. The basic reason for a protective tariff is to keep out goods that will undersell products made in the home country. For this reason, protective tariffs are often very high, thus forcing the foreign business to raise its prices to cover the tariff.
