The feature was made available immediately on millions of mobile phones that can access the web,such as the BlackBerry.Within weeks Google hopes to launch a new one that wilt also work on computers as well.

Q: Article: The Dixie Chicks used to be known as the biggest-selling female group in music history. Now they are known as one of the most disputed . In 2003, Natalie Maines, the lead singer of the Dixie Chicks, was in the news. During a concert in London, she criticized President Bush for his political actions. She spoke less than two weeks before the invasion of Iraq. The Chicks did not realize the effect of those words. They soon lost their fans. They even received death threats. The comment changed the direction of their lives, music, and beliefs. Now, their new album Taking the Long Way shows their new musical direction. It is about acting and thinking freely. Maines openly sings about criticizing the president. She says she learned about herself by expressing her beliefs. The album also represents the Chicks' new musical style. In the past, they only sang songs influenced by country music. They did not always write their own music.
