A E-GAMES John and Stephanie both wanted a complete career change. Selling children's games over the internet seemed a foolproof idea, but their biggest challenge was to secure financial backing. First they contacted numerous venture capitalists, but from the response of the few that would even talk to them, they realised they would get nowhere until they had spelt out in detail how they intended to turn their concept into reality. So the next step was to work with a group of start-up consultants, to devise a business plan making their expected revenue streams more precise. B SUREK Sue and Derek's plan was to sell clothes over the internet. After a shaky start, leading to serious cash flow problems, which meant they occasionally had little to live on, they realised they would have to advertise much more seriously: on the internet, they used online marketing tools to the full to produce increases in traffic, and combined this with intensive publicity outside the internet. Within six months they had built a large customer database, at which stage it was necessary to begin looking for capital to build the business. C WONDERWEB Two senior advertising executives, frustrated with the pace of change in an industry they felt was failing to take advantage of new media, Sally and Sue were keen to translate their advertising and marketing skills into an online environment. To their surprise, they found that many websites seemed to have been developed without taking any account of users' needs. Sure that the opportunity was ripe for a business with a strong marketing proposition, they started offering marketing services to other small online businesses. D SUPERGIFTS Michael and Tony set up a company to sell up market gifts, such as glassware and porcelain, online. The niche market they have identified is professional and affluent, a group which their research revealed is increasingly internet literate, is looking for exceptional goods at the right price and has high service expectations. A low-level marketing campaign generated more than 2000 customers, with a high-value average order. The entire system from web order to delivery is proving to be highly successful, with all orders being fulfilled within the advertised five days without any returns or breakages. E ABBIE'S The first phases of the company's growth have been funded through a mix of personal investment, foregone salaries and bank overdraft. The next phase will be crucial. Their biggest challenge will be to distinguish themselves from a plethora of competitive sites, most of which are spending far more than they are. To stand out from the crowd, Paul and Abbie are working to target and reach their audience better, and generate higher sales, but of necessity without increasing their budget. The company's total marketing vision will be the key to success. These people have not paid themselves out of their company's income so far.

？For each question 15—20, mark one letter (A, B, C, or D) on your Answer Sheet for the answer you choose. Cooperative cooperation. Competitive cooperation. Confused？ Airline alliances have travelers scratching their heads over what's going on in the skies. Some folks view alliances as a blessing to travelers, offering seamless travel, reduced fares and enhanced frequent-flyer benefits. Others see a conspiracy of big business, causing decreased competition, increased fares and fewer choices. Whatever your opinion, there's no escaping airline alliances: the marketing hype is unrelenting, with each of the two megs-groupings, One world and Star Alliance, promoting itself as the best choice for all travelers. And, even if you turn away from their ads, chances are they will figure in any of your travel plans. By the end of the year, One world and Star Alliance will between them control more than 40% of the traffic in the sky. Some pundits predict that figure will be more like 75% in 10 years. But why, after years of often ferocious competition, have airlines decided to hand together？ Let's just say the timing is mutually convenient. North American airlines, have exhausted all means of earning customer loyalty at home, have been looking for ways to reach out to foreign flyers. Asian carriers are still hurting from the region-wide economic downturn that began two years ago-just when some of the airlines were taking delivery of new aircraft. Alliances also allow carriers to cut costs and increase profits by pooling manpower resources on the ground and cede-sharing—the practice of two partners selling tickets and operating only one aircraft. So alliances are terrific for airlines—but are they good for the passenger？ Absolutely, say the airlines: think of the lounges, the joint FFP (frequent flyer program) benefits, the round-the-world fares, and the global service networks. Then there's the promise of "seamless" travel= the ability to, say, travel from Singapore to Rome to New York, all on one ticket, without having to wait hours for connections or worry about your hags. Sounds utopian？ Peter Buecking, Cathay Pacific's director of sales and marketing, thinks that seamless travel is still evolving. "It's fair to say that these links are only in their infancy. The key to seamlessness rests in infrastructure and information sharing. We're working on this. n Henry Ma, spokesperson for Star Alliance in Hong Kong, lists some of the other benefits for consumers. "Global travelers have an easier time making connections and planning their itineraries. ' Ma claims alliances also assure passengers consistent service standards. Critics of alliances say the much-touted benefits to the consumer are mostly pie in the sky, that alliances are all about reducing costs for the airlines, rationalizing services and running joint marketing programs. It is believed that alliances will ultimately result in decreased flight choices and increased costs for consumers. Instead of two airlines competing and each operating a flight on the same route at 70% capacity, the allied pair will share the route and run one full flight. Since fewer seats will be available, passengers will be obliged to pay more for tickets. Those who've already made the elite grade in the FFP of a major airline stand to benefit the most when it joins an alliance: then they enjoy the PFP perks and advantages on any and all of the member carriers. For those who haven't made the top grade in any FFP, alliances might be a way of simplifying the earning of frequent flyer miles. For example, I belong to United Airline's Mileage Plus and generally fly less than 25,000 miles a year. But I earn miles with every flight I take on Star Alliance member-Ail Nippo A．Delight.

The warning came as the website run by SCO, a company that sells Unix computer software, in effect disappeared from the web under a blizzard of automated attacks from PCs infected by the virus, which first appeared a week ago. The "myDoom-A" version of the virus is reckoned to be the worst to have hit the internet, in terms of the speed of its spread, with millions of PCs worldwide believed to be infected. Such "zombie" machines begin to send out hundreds of copies of the virus every hour to almost any e-mail address in their files. On Sunday they began sending automated queries to SCO's website, an attack that will continue until 12 February. The attack is the web equivalent of ringing the company's doorbell and running away a million times a second, leaving its computers unable to deal with standard requests to view its pages. "You have to wonder about the time limit," said Graham Cluley, senior technology consultant at the antivirus company Sophos. "Someone could go to SCO after the 12th and say, 'If you don't want this to happen again, here are our demands'." Raimund Genes, European president of the security software firm Trend Micro, said: "Such a programme could take out any major website on the internet. It's not terrorism, but it is somebody who is obviously upset with SCO." SCO has earned the enmity of computer users through a lawsuit it has filed against IBM. SCO claims ownership of computer code it says IBM put into the free operating system Linux, and is demanding licence fees and damages of $1bn. Mr. Cluley said: "It might be that whoever is behind this will say to SCO, 'if you don't want the next one to target you, drop the lawsuit'." SCO has offered $250,000(￡140,000) for information leading to the arrest of the person or people who wrote and distributed MyDoom. Nell Barrett, of the security company Information Risk Management, said, "I would give a lot of credence to the idea of gangs using viruses to extort money. It's hard for law enforcement to track them down, because they're using machines owned by innocent people." A second variant of MyDoom will start attacking part of Microsoft's website later today. The antivirus company MessageLabs said it had blocked more than 16 million copies of the virus in transit over the net so far. But millions more will have reached their targets. The onset of a new generation of computer attacks was marked by ______. A．an organization of gangs B．the infection of PCs C．the sale of a software D．a website's vanishing
