A client media player can begin playing the data (such as a movie) before the entire file has been transmitted. Distinguishing delivery method from the media distributed applies specifically to [[telecommunications network]]s, as most of the delivery systems are either inherently streaming (e.g.,&nbsp;[[radio]], [[television]]) or inherently nonstreaming (e.g.,&nbsp;[[books]], [[Videotape|video cassettes]], audio [[Compact Disc|CD]]s). For example, in the 1930s, [[elevator music]] was among the earliest popularly available streaming media; nowadays [[Internet television]] is a common form of streamed media. The term "streaming media" can apply to media other than video and audio such as live [[closed captioning]], [[ticker tape]], and [[real-time text]], which are all considered "streaming text". The term "streaming" was first used in the early 1990s as a better description for [[video on demand]] on IP networks; at the time such video was usually referred to as "store and forward video",<ref>{{cite web| url = http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=188525&url=http%3A%2F%2Fieeexplore.ieee.org%2Fiel2%2F536%2F4777%2F00188525.pdf%3Farnumber%3D188525| title = On buffer requirements for store-and-forward video on demand service circuits | accessdate =| publisher = [[IEEE]]}}</ref> which was misleading nomenclature.
