History.
A strongly held belief in ancient Babylon, astrology spread to the Mediterranean world, and was widely used by the Greeks and Romans. In Europe during the Middle Ages it had a powerful influence, since kings and other public figures had their own astrologers; astrological beliefs are reflected in Elizabethan and Jacobean literature.
In Chinese and Hindu thought, the universe is seen as forming a pattern in which everything is linked. Human life should be lived in harmony with this pattern, and astrology is seen as one way of helping to do this.
In the US, horoscopes are syndicated in most newspapers and almost everyone, whether professing belief or not, knows his or her astrological sign.
