From Wikipedia: 

The New International Version (NIV) is an English translation of the Bible first published in 1978 by Biblica (formerly the International Bible Society). The NIV was published to meet the need for a modern translation done by Bible scholars using the earliest, highest quality manuscripts available. Of equal importance was that the Bible be expressed in broadly understood modern English.

The NIV is published by Zondervan in the United States and Hodder & Stoughton in the UK. The NIV was updated in 1984 and 2011 and has become one of the most popular and best-selling modern translations.
