The most powerful carrier of information ever created isn’t a highway at all. It’s a super skyway. And it exists today—a satellite network that is ubiquitous(普遍存在的), reliable and worldwide.
Unlike fiber optics(纤维光学), satellites can send data to any point on earth, at sea or in the air—all at the same time. Nor are they vulnerable(易损的) to great natural disasters like hurricanes and earthquakes.
Satellites are cost-effective whether they’re beaming information across towns or across oceans. And they are essential for today’s broadcast, cable, business, TV, radio, data transmission, educational programming and telephony industries.
The information highway is changing rapidly, but satellites will continue to provide the necessary fast lane. For a free brochure(小册子) on how satellites can help your business, call us at 5422538.

When the first bakers found that they could make a soft, spongy(多乳的) bread rather than a firm, thin cracker they we’’re acting as fledgling(缺乏经验的) biotechnologists.
