What is the procedure of seven wonders selection in SMS?

Answer 1

The new Seven Wonders of the World was compiled by popular vote over a six year period by a nonprofit group headed by Swiss adventurer Bernard Weber. In 1999 Weber began collecting suggestions from internet users around the world. A list of over 200 nominations was narrowed down to 70, and then to 21, and finally to 7 (Chichen Itza, Taj Mahal, Christ the Redeemer, Colosseum of Rome, Great Wall of China, Machu Picchu and Petra). The group reported more than 100 million votes, received via the Internet and cell phone messages, which, if true, makes this the largest poll ever conducted.
