Presentation Title: Telecommunication

Specific Purpose: To inform my audience about the AT&T’s contribution to telecommunication industry.

Thesis Statement: AT&T’s innovative development of the transatlantic radiotelephone and communication satellite changed communication and inspired new inventions that would shape the future of the world.

INTRODUCTION

I. Attention Getter: The first time I came to the United States, I was so excited to share the beautiful sceneries with my family that I mailed a postcard back home from Los Angeles. I was looking forward hearing their comments that I checked every time when I called home if the postcard had arrived. But the answers were always no. However, after I had been back home for a whole week, I found the “fresh” postcard actually just arrived in the mailbox. After viewing the pictures I took, the postcard wasn’t that impressive to my family as I imagined, which was really disappointing. II. Credibility Statement: As one of the millions of users of the transatlantic telecommunication service, I am grateful to those who contributed to it. Not only me, but governors, business managers, and academic scholars speak highly of the telecommunication system, because it gives us a better chance to expand our horizons. III. Relating to the audience: Have you checked out the free courses that Yale University recently uploaded? Have you heard about the news of the 2012 Olympic Game in London from BBC new recently? Have you talked to a friend who is studying abroad through computer of cell phone? Noticed or not, telecommunication acts as an influential part in our lives. IV. Thesis Statement: AT&T’s innovative development of the transatlantic radiotelephone and communication satellite changed communication and inspired new inventions that would shape the future of the world.

Directional transition: When did AT&T begin to play such an important role in the telecommunication history? We may find our answer from its innovational development process.

BODY
AT&T inaugurated the first transatlantic telephone service with a single radiotelephone circuit establishing a milestone in the telecommunication history. (Rcorlburn, 2008) A. On January 7th, 1927, first phone call between the US and the UK was made by AT&T’s president who uttered “ Hello London.” (History Central, 2000) 1 . It took 50 years from the invention of the telephone to make transatlantic phone calls. (Connected Earth, 2010) a. Alexander Graham Bell said the first spoken sentence ever transmitted via electricity into his experimental telephone on March 10, 1876. (AT&T, 2010) 2. The conversation crossed the Atlantic via radio on January 7th 1927. The initial capacity is one call at a time at a cost of $75 for the first three minutes. (AT&T, 2010) a. $75 in 1927 has the same buying power of $939.70 today.(Bureau of Labor Satistics, 2010) b. Depending on where you call, the cost of a transatlantic call today could be as cheap as $0.15 per minutes. (AT&T, 2010) B. Since then, AT&T spreads its business over 220 countries whose convenience users is up to 90.1 million nowadays. (AT&T, 2010) 1. AT&T enables people from the US to call or text to another country. 2. AT&T enables people from the US to travel abroad with their cell phone in use, which benefits a lot of business professionals. C. “While radio circuits provided a voice service, the vagaries of sunspot and seasonal and daily variations were never overcome entirely. Moreover, radio did not guarantee its users privacy and security.”(Rcrolburn, 2008)

Directional Transition: The limitation of radiotelephone is never a hold back of the development of telecommunication, but shed new light on the...
