However, that was an exception. Just consider HTTP1.1. This new browser protocol is finally slowly moving towards dominance, half a dozen years since its inception. IPv6, the new Internet protocol designed to solve several technical problems, including that of limited address space, is still only being used on a small scale, although it is about as old as HTTP1.1. These three examples are not aberrations.
Internet telephony is another example that easily comes to mind.
Already in 1995 it was predicted to bring imminent doom for the established phone companies, but it is barely noticeable today. Similarly, eBay, for all its successes, has so far had little impact on the classified ads that sustain newspapers. All these technologies and companies are transforming the economy, but not in Internet time. The general rule is that it takes around a decade for even a compelling new product or service to be widely accepted. Of course, that was decades ago, prehistoric by the standards of Internet time.
