History

On March 10， 1876， Alexander Bells first successful transmission of voice by telephone lines marked the arrival of phone era. On that day， Bell accidentally knocked off and splashed some sulfuric acid on his clothes in the laboratory， so he summoned his assistant Watson loudly： "Mr Watson， come here， I need you！" It then became the first sentence transmitted through telephone line.
