> TV made radio obsolete.
And yet, I hardly ever see a car without one, advertisers still buy
time on radio, two companies launched completely new radio
services long after TV had been around for several years
(XM and Sirius). I would say TV did not make radio obsolete
since radio is still going strong. Radio is not a niche.
> CDs made vinyl obsolete.
True to some extent, but, there is still a strong contingent of
people who prefer vinyl and a resurgence of vinyl collectors
occurs from time to time.
> The automobile made
> horses obsolete.
As a primary mode of transportation, sure. OTOH, horse racing,
and other recreational equestrian activities are still going strong.
In fact, in many ranching applications, horses are still preferred
over motor vehicles.

NetBEUI was pretty wide-spread at one point, and, has since
died out _VERY_ quickly.
If we can learn anything from history, it is that mass market moves
are incredibly difficult to predict and planning the obsolescence
of a high-demand technology is virtually impossible.
