On The New York Times I read the following sentence:
The bad news here begins with the economy, which stinks. This is the
epicenter of the dot-bomb, the edge of the ailing Pacific Rim and
now a major casualty of tourist malaise.
What does dot-bomb mean?
It’s referring to the economic collapse of the “dot-com” boom, which occurred in the late 1990s. This Wikipedia article explains it rather well.
