Article: After months of fear, hate and prosecution , the music and consumer-electronics industry decided to try to make beautiful music together. Last week the Secure Digital Music Initiative, a combination of 100 music, electronics and high-tech companies announced that it agreed on a music format known as MP3 which caused disagreement. Nowadays, more and more young people are fond of music that is played on their portable MP3 players. So this announcement attracted a lot of attention in both the producer and consumer sides. MP3 allows the digital music in CDs to be made smaller to a tenth its size and still sounds great. MP3 songs are small enough to be traded online; they are made by the millions to the _ of record companies, which fear that everything ever released on disc will end up online for free. Traditional records and their sale may be greatly damaged by this new format of music, and for the music's sake, it is better conveyed in this new medium. That's why the recording industry appealed to the court against little Diamond Multimedia when it started selling a portable MP3 player two years ago. Not only did Diamond win in court, but it also sold 100,000 Rios along the way. With half a dozen other companies racing to produce their own versions of the Rio for Christmas, what could the music industry do? They have no choice in their future, their success just depends on how they can deal with the new trend and cooperate with the electronics companies. It couldn't ignore MP3, which has become the format of choice among new bands trying to advertise their pre-released songs. So the industry agreed on it on one condition: within 18 months, when a standard is adopted that allows piracy-protected music (free from being illegally copied) to be sold online, the electronics companies agree to make their players in line with it. This clears the way for the new magic MP3 players, which is both convenient and capable of carrying on much more music than traditional walkmans. What's next? Digitally pirated movies. Get ready,prefix = st1 /Hollywood.

Article: In the social and economic fields the UN increased its efforts to fight against poverty, ignorance, hunger, and disease and to help raise the standards of living in the newly developing countries. The sixteenth General Assembly placed considerable emphasis on the idea of economic development by planning the current decade as the United Nations Decade of Economic Development. The agreement called upon UN members to help the newly developing countries achieve a minimum rate of growth of 5% by the end of the decade. It also emphasized the need for industrial development and encouraged cooperation with respect to regional-development programs. In the past the organs and agencies of the UN in the economic field have concentrated largely on economic development. Increased attention was directed towards the need for balance and integration in economic and social development. It was emphasized at various UN meetings that particular attention must be given in the new nations to such problems as urbanization, housing, community development, and child welfare. The Assembly has also offered a $100,000,000 world food program designed to use surplus food to encourage the development of needy countries. The program would improve upon the present unsatisfactory method of disposing of surplus food supplies and would enable the poorer nations to use more of their resources for development purposes. Many of the UN specialized agencies increased their budgets. This means that such agencies as the Food and Agriculture Organization, the United Nations Educational, Scientific, and Cultural Organization, the World Health Organization, and the International Labor Organization will be pushing ahead at an increasing rate to deal with problems in their respective fields. The Assembly again set $150,000,000 as the target figure for the work of the UN Technical Assistance Program and the Special Fund. If funds are available, technical assistance will move ahead at a faster speed.
