About "Vaporware" TV Shows

There are some instances that a trailer of an upcoming TV show is shown but it takes too long to bring the show on the air. Such a show is considered a "vaporware" TV show. The occurrence of vaporware TV shows are common in Asia and Africa. A typical vaporware TV show takes much time to put it on the air after its initial announcement. In some cases, the staff cancels a vaporware TV show before its pilot episode. For example, a TV company airs trailers of a vaporware TV show and when seems nothing happened to the show, the staff just cancels the TV shows. Another example that a TV company launches the pilot episode of another TV show a few years in the making.

That's it. I am accepting any comments on this post.
