means Exaggerated excitement or promotion designed to build anticipation for something, usually faster than the thing itself can earn it.

from Most likely a clipped form of 'hyperbole,' shortened in 20th-century American slang. By the 1920s 'hype' was carny and con-artist jargon for a swindle or a drug addict (as in 'hypodermic'), and by mid-century it had drifted into show business and advertising to mean inflated promotion — the needle-fast rush of enthusiasm replacing the slower, more honest buildup of proof.
