How communication has changed in the last 30 years.
Answers
Answer:
Over the past 30 years, more and more satellites have been launched into orbit, primarily for television and telephone service. ... Called the Global Positioning System (GPS), the satellite network would revolutionize how we communicate. Think back to how we communicated 30 years ago. Chances are, you used a telephone — one with a cord attached to it and plugged into the wall — and you wrote letters. Today, we have cell phones, pagers, wireless mobile devices, and personal computers or laptops — all with access to the Internet. Today, we communicate via e-mail, instant messaging, and online chat rooms. We communicate in ways that were not even imaginable 30 years ago, and now we can’t imagine how we ever lived without these technologies.
Just over 30 years ago, Dr. Martin Cooper, a former general manager at Motorola, invented the first portable telephone handset, and became the first person to make a call on a portable cell phone in 1973. Dr. Cooper wanted everyone to be able to carry their telephones with them, and to be able to communicate with each other from anywhere. The first Motorola cell phone weighed 2.5 pounds, had talk time of 35 minutes, contained 30 circuit boards, and cost about $3,500. Today, it is deemed unusual not to have a cell phone, and Dr. Cooper’s vision of everyone being able to communicate from anywhere, anytime, is now a reality.
