They pretty much all failed or were made to fail (DigiCash[0], Flooz, e-gold, etc.) or were subsumed into the existing system (eg. PayPal). As far as I can tell, the big picture hope this time around is that the existing system will be subsumed into one or more successful cryptocurrencies, rather than the other way around (which defeats the decentralization). [0] DigiCash was an anonymous, nominally distributed, system, which is a different set of properties than current cryptocurrencies.
