How Does An Integrated Amp Differ From A Receiver?

Traditionally a receiver meant it had built in radio tuner, usually for am and fm.
However have also seen receivers that had just dbb radio ?
Mapman has a point that any that stream internet radio could also conceivably be called a receiver.

Not really many new traditional receivers built right now, at least nowhere near the amount of integrated which are having quite a bit of a resurgence.

The term "receiver" derives from the concept of a radio receiver which typically had facilities for audio amplification for playback. They don't call them tuners in HAM circles. They're receivers. The tuner portion of a good old receiver will consume a quarter to a third of the electronics and they were much better quality than what you get in today's black plastic faced boxes. 

Suddenly I feel quite old knowing this term needs clarification.

If its got a radio-tuning dial it's a RECEIVER!
