What is Entertaiment?
Entertaiment is a fun, playful word, and it is well used in many different contexts. It is a term that can be adapted for an individual who selects entertainment from a mass selection of pre-recorded products, to a banquet adapted for two, to performances intended for thousands, and even to global audiences. It is also a term that is continually evolving, and activities such as cooking that were once utilitarian have now been developed into spectator sports. You may see the word entertainment abbreviated to entmt on some industry news fliers or in short hand note taking.
