What is regarded as canonical text differs depending on traditions and groups; a number of Bible canons have evolved, with overlapping and diverging contents. The Hebrew Bible overlaps with the Greek Septuagint and the Christian Old Testament. The Christian New Testament is a collection of writings by early Christians, believed to be mostly Jewish disciples of Christ, written in first-century Koine Greek. Among Christian denominations there is some disagreement about what should be included in the canon, primarily about the Apocrypha, a list of works that are regarded with varying levels of respect.
The Bible has been a massive influence on literature and history, especially in the Western World, where the Gutenberg Bible was the first book printed using movable type. According to the March 2007 edition of Time, the Bible "has done more to shape literature, history, entertainment, and culture than any book ever written. Its influence on world history is unparalleled, and shows no signs of abating." With estimated total sales of over 5 billion copies, it is widely considered to be the most influential and best-selling book of all time. As of the 2000s, it sells approximately 100 million copies annually
