"Doomed" to me doesn't sound like "not expected to grow". It sounds more like "expected to die off". I mean, tv sales have been dropping for the last few years, but we're not saying the tv market is doomed because we don't expect that market to die. I think a better word for "not expected to grow" is "saturated".

In any case, the use of the word "doomed" is hyperbolic or at the very least ill defined scaremongering.
