History of Twitter
They were looking for a way to send text on their cellphones and a way to reinvent a dying company. On March 21, 2006, @Jack sent the first tweet: "just setting up my twttr." And thus a communications revolution was born, one renown for brevity and bad spelling. Dom Sagolla (@Dom), in tweet 38, typed these prescient words: "Oh, this is going to be addictive."
THAT NAME
The name Twitter was inspired by Flickr, a photo-sharing service. Other names considered: FriendStalker and Dodgeball. The dictionary definition of twitter is "a short burst of inconsequential information."A perfect name, said @Jack because "that's exactly what the product was."
TWITTER TODAY
Almost 200 million users worldwide. About 460,000 new Twitter accounts are opened daily. More than 140 million tweets are sent daily. That's one billion weekly. In 2008, Twitter had eight employees; today it has more than 400. And they're hiring (twitter.com/jobs)
WHY 140 CHARACTERS?
At the heart of Twitter are small bursts of information called tweets. Each tweet is 140 characters in length, maximum. Initially, there was no limit to message length. When it went public, the 140 character limit was adopted. Why? Because 160 characters was the SMS carrier limit and the founders wanted to leave room for a username. Struggling with brevity? You can purchase 140 Characters: A Style Guide for the Short Form by @Dom.
HOW TWITTER MAKES MONEY
Twitter lists its revenues at a modest $150-million annually. It is a private company so the sources of revenue are unclear. Twitter also licenses its stream of tweets to Microsoft, Google and Yahoo. There are constant rumours that Twitter will be purchases by Facebook or Google. It could also go public like LinkedIn. Twitter is said to be worth more than $4.5-billion. The value comes from its potential to exploit its base of hundreds of millions of users. Twitter could sell traditional ads (not likely) and to start charging for premium accounts that push business to their sites (very likely).
HOW TWITTER HAS CHANGED THE MEDIA
Twitter is not just your friends telling you what they ate for breakfast. Increasingly, news stories that arise - a tsunami, a plane crash, the score of a hockey game, the latest Charlie Sheen gossip - arrive in tweets from people we follow on Twitter. This allows everyone to essentially create their own newspaper or newscast, and to do so instantaneously.

The history of america
American History
1700-1799
- The American Revolution (sometimes referred to as the American War of Independence or the Revolutionary War) was a conflict which lasted from 1775-1783 and allowed the original thirteen colonies to remain independent from Great Britain.
- American politician and soldier George Washington became the first President of the United States in 1789, serving two terms.
- Beginning in Great Britain in the late 1790s, the Industrial Revolution eventually made its way to the United States and changed the focus of our economy and the way we manufacture products.
1800-1899
- In 1803, President Thomas Jefferson agreed to the Louisiana Purchase, successfully adding 530 million acres of land to the United States. The area was purchased from France for $15 million. The following year, President Jefferson assigned Meriwether Lewis (who asked for help from William Clark) to head west and explore the newly purchased land. It took about a year and a half for the duo to reach the west coast.
- The American Civil War divided the United States in two – the Northern States versus the Southern States. The outcome of the four year battle (1861-1865) kept the United States together as one whole nation and ended slavery.
1900-1999
- On December 17, 1903, brothers Wilbur and Orville Wright became the first people to maintain a controlled flight in a powered, heavier-than-air machine. The Wright Flyer only flew for 12 seconds for a distance of 120 feet, but their technology would change the modern world forever.
- On April 6, 1917, the United States entered World War I by declaring war on Germany.
- After nearly 100 years of protests, demonstrations, and sit-ins, women of the United States were officially granted the right to vote after the 19th Amendment was ratified on August 26, 1920.
- The worst economic crisis to happen in the United States occurred when the stock market crashed in October 1929 resulting in the Great Depression.
- World War II officially begins in September 1939 after Germany invades Poland. The United States didn’t enter the war until after the Japanese attack on Pearl Harbor on December 7, 1941.
- On August 6 and August 9 1945, the United States dropped an atomic bomb on the Japanese cities of Hiroshima and Nagasaki, effectively ending World War II.
- After World War II, an agreement was reached to divide Korea into two parts: a northern half to be controlled by the Soviet Union and a southern half to be controlled by the United States. The division was originally meant as a temporary solution, but the Soviet Union managed to block elections that were held to elect someone to unify to country. Instead, the Soviet Union sent North Korean troops across the 38th parallel leading to the three-year long (1950-1953) Korean War.
- From 1954-1968, the African-American Civil Rights movement took place, especially in the Southern states. Fighting to put an end to racial segregation and discrimination, the movement resulted in the 1964 Civil Rights Act, the 1965 Voting Rights Act, and the 1968 Fair Housing Act.
- The Vietnam War was a nearly 20 year battle (November 1, 1955–April 30 1975) between North Vietnam and South Vietnam. North Vietnam won the war and Vietnam became a unified country.
- The Apollo 11 mission (July 16-24, 1969) allowed United States astronauts Neil Armstrong and Edwin “Buzz” Aldrin to become the first humans to walk on the moon’s surface.

The history of titanic
Titanic was one of three 'Olympic Class' liners commissioned by the White Star Line to be built at the Harland and Wolff shipyard in Belfast. Construction began on the first of these great ships, Olympic, on 16 December 1908. Work on Titanic started soon after, on 31 March 1909. These magnificent vessels were the industrial marvels of their age and Titanic was to be the biggest, fastest and most luxurious liner yet. After just three years, Titanic was finished - a floating city, ready to set sail on her maiden voyage from Southampton to New York. On board was a collection of passengers comprising millionaires, silent movie stars, school teachers and emigrants, in search of a better life in the United States. By the fifth day of its journey, Titanic was making swift progress across the Atlantic. Although Captain Edward Smith had plotted a new course upon hearing earlier reports of ice from other liners, there were many more communications that day of ice in Titanic's path. On the night of Sunday 14 April 1912, the sea was flat calm, the sky clear and moonless, and the temperature was dropping towards freezing. In such conditions, sea ice is very hard to spot. At 11.40pm the lookout sounded the alarm and telephoned the bridge saying "Iceberg, right ahead." The warning came too late to avoid the iceberg and Titanic struck it less than 40 seconds later, tearing a series of holes along the side of the hull. Upon inspecting the damage, Titanic's chief naval architect Thomas Andrews said to Captain Smith that the ship would certainly sink. Six of the watertight compartments at the front of the ship's hull were breached, five of them flooding within the hour. Titanic was designed to stay afloat with only four compartments flooded. Less than three hours later Titanic lay at the bottom of the Atlantic ocean, nearly four kilometres down. The sinking of Titanic claimed more than 1,500 lives. For many, the tragic fate that befell Titanic would come to mark the passing of the opulence of the Edwardian era and foreshadowed the global tragedy of World War One. The story captured the public imagination across the world, spawning countless books, films, plays, memorials, museums and exhibitions. The discovery of the wreck by oceanographer Robert Ballard on a Franco-American expedition in 1985 gave rise to a fresh wave of interest that continues to this day.

The Prehistoric Period
Sri Lanka’s past climatic fluctuations for about 500,000 years have been delineated on the basis of those investigations and co-related with the evolution of Sri Lanka’s Stone Age. In his research, cultures have been studied in terms of stone tool technology, subsistence practices, settlement patterns, burial practices and physical anthropology. These studies have pioneered climatologist studies in South Asia and in the Tropics in general. It seems that for the first time it is securely established that humans of the old Stone Age have inhabited Sri Lanka as early as 125,000 years ago and possibly 500,000 or more.
