same way. Story by The MBA describes story as "distinct from [teleplay/screenplay] and consisting of basic narrative, idea, theme or outline indicating character development and action". A "Story by" credit is used when the writer was hired (as a WGA member) to write for story, when the story idea was purchased from the writer by a WGA signatory company, or when the resultant script is based on a sequel story devised by the writer under the WGA's jurisdiction. The "Story by" credit cannot be shared by more than two writers in film and three in television, and the story may have been written in different literary forms, including a film treatment. A "Screen Story by" or "Television Story by" credit is used for the screenwriter when their work is based on, but substantially different from, source material and a story as they are defined by the WGA. Screen story credit also cannot be shared by more than two writers, and is a credit that is only handled through arbitration. The writer of the source material for the screen story may receive a source material credit. Separated rights Television also has a "Created by" and a "Developed (for Television) by" credit under a crediting structure known as separated rights. Writers entitled to created by credits will have developed a significant part of the format, story, and teleplay, and also get sequel rights to the material. Created by credits are given on every episode, while Developed (for Television) by credits are only given on the episodes the writer has explicitly contributed material to. Other forms Other writing credits that may be used are "Narration Written by", "Based on Characters Created by", and "Adaptation by". A "Special Material by" credit can be given to writers on some forms of television shows, when they have contributed written material that does not qualify for other credits; there are no limits to how many people may receive this credit. Screenwriter Scott Myers, a WGA member and arbiter on "perhaps 10 credit arbitrations", has questioned why more than three writers cannot be credited, saying: Structure and exceptions In credits, names are usually ordered by who did the most work. If the order is disagreed upon and the arbitration finds that all writers contributed equally, the names will be ordered chronologically. A pseudonym may be used if the writer is to be paid less than (for film) or
