Alienware is unknown to most of people. I don’t know if they care to sell their product or they want to keep their company secret. Their commercial lacks information of the product. I believe that they make advertisement to increase their sales and spread their name to public in same time. Alienware might be successful in spreading their name but, their sales won’t increase as much as other PC brands out in the public. To increase the sales effectively, Alienware should put detail information in their commercial, so consumers could learn more about Alienware product. Advertisement has to have many qualities to deliver their purpose effectively. It has to be humorous and entertaining, so consumers would remember the commercial for long time. Also it should contain enough information of the product so consumers get the idea of item that company is trying to sell. Alienware lacks all of these qualities, and if they want to become popular and compete with some other successful PC brand, they should improve their commercials with qualities that consumers want to know.

Global warming to cause shortages in Asia, Africa and Latin America, draft report warns

WASHINGTON–Harmful effects of global warming on daily life are already showing up and within a couple of decades hundreds of millions of people won't have enough water, top scientists will report next month in Belgium.

At the same time, tens of millions of others will be flooded out of their homes annually as the earth reels from rising temperatures and sea levels, according to portions of a draft of an international scientific report obtained by The Associated Press.

Tropical diseases like malaria will spread. Pests like fire ants will thrive. But, by 2050, polar bears will mostly be in zoos, their habitats gone.

For a time, food will be plentiful with a longer growing season in northern regions. But by 2080, hundreds of millions of people could face climate-related starvation, according to the report, still being revised.

The draft by the authoritative Intergovernmental Panel on Climate Change focuses on global warming effects and is the second of four being issued thi
