The dot-com bubble occurred from 1997-2000 as many new internet companies went public and stock prices rose rapidly based on speculation about future profits rather than current earnings. The bubble burst in 2000 as stock prices declined sharply, many internet companies failed or went bankrupt, and the US economy entered a recession. While new technologies stimulated growth and consumption during the boom, the collapse had widespread economic impacts and opened the recession of the early 2000s.
