The internet as we know it today was developed  in the late 1960s to enable the US military and the UD government to access each other’s computers. The first email program was created a few years later, in 1972. But the World Wide Web wasn’t set up until 1993 – with just 100 websites. The Web grew at a phenomenal rate and in 1994, Pizza Hut became the first retailer to offer online ordering. Online banking and other financial services were introduced in the same year. There are now over  ten billion web pages and over a hundred thousand new ones are added each week. The Google search engine was launched in 1998 and today around a billion searches widely available in 2003 and today over a million songs are downloaded every hour. The internet is used regularly by over a billion people worldwide.

American English spelling

Most of the spelling differences between American and British English were made shortly after American Independence in 1776. And the individual who is considered most responsible for the “Americanization” of English spelling was the lawyer, writer and fervent nationalist Noah Webster(1758-1843).

In the late 1700s, America was a new country and Webster wanted to promote an American sense of identity. Among other things, he believed that America should have its own standards of English which were different from the English of the recently-departed British colonists.

Spelling changes were the easiest aspect of the language to “Americanize” and Webster and his team of like-minded writers and academics set about initiating the revolution. Basically, “silent” letters were removed (colour-color, dialogue-dialog, etc.) and spelling was made more literal and phonetic( centre-center, grey-gray,etc.).

In 1783, Webster began publishing school textbooks and his new “American” spellings were rapidly accepted. His textbooks were in fact used  in schools for the next  100 years. In 1793, Webster published New York’s first daily newspaper and in 1828 he published An American Dictionary of the English Language, which is still published today.

Performance halted by mobile

When a mobile phone during a performance of the History Boys at New York’s Broadhouse Theatre last night, lead actor Robert Griffiths stopped the scene and shouted at the offending audience member, “You are told to turn them off by the stage manager; he told you it was against the law. If we hear one more phone, the performance will be cancelled.” The law to which Griffiths referred is a ban on using mobiles in all theatres, museums, galleries and libraries in New York, which was passed in 2003. Violators of the law are fined $50.

Mobiles go back to the future

They can play music, connect to the internet and take photographs and videos, but today’s mobile phones are simply too complicated for many older people. In response, a new telephone has been introduced which has none of these added extras; you can make and receive calls and nothing more. The PhoneMe Simply, which was designed mainly for the over 55s, is twice the size of most of today’s mobiles and has a large screen and large buttons. Features such as battery and signal strengthexplains in words rather than by symbols, which can confuse older users. In Japan, a similar phone which went on sale last year became the fastest selling mobile this century.

A winning argument

A pizza restaurant has been ordered to pay Amy Moore of Brooklyn, New York, $15,000 after she slipped on a soft drink and was knocked unconscious. The restaurant owner protested against the award as the beverage was on the floor because Ms Moore had thrown it at her boyfriend two minutes earlier during an argument. However, the judge ruled that the restaurant was at fault because the drink should be cleaned up immediately. Ms Moore was banned from the restaurant for life for her ‘unacceptable public behaviour’.

‘La Gioconda’ is probably the most famous painting of all the time. It was painted by Leonardo Da Vinci over 500 years ago and her image is the most copied in the history of art.

The woman in the picture is believed to be Lisa GherardiniGiocondo, who was born in Florence in 1479. She is thought to have been 24 when Leonardo painted her. Her legendary and enigmatic features, especially her smile, were created by the process of sfumato, a style of painting which was invented by the artist. Da Vinci took four years to complete the painting.

At the beginning of the 1500s, the painting was bought by King Francis I of France and was taken from Italy to Paris. In 1650, the painting was moved to the Louvre, which was the royal palace. In 1911, it was stolen by a Louvre employee, who walked out of the museum with it under his coat.

‘La Gioconda’ is believed to be valued $1 billion. However, it will never be sold. Today, the painting attracts about six million visitors a year.
