"One by one, an explanation of these unlucky thirteen factors, which are divided into eight categories: DOA (pre-production problems, script and cast changes), Corpse (not enough buzz and hype, postponing the return date, no lead-in), Incision (schedule changes, hiatus), Diagnosis (no additional episodes or full season orders and early renewals), Dissection (cut back on episodes orders/premature orders), Burial (pulled from schedule early in advance) and Casket, (pulled from schedule effective immediately, all leading to Flatlines (ratings)."

Above are reasons and factors that go into canceling a show. One of them emphasized points on the American Idol chapter focuses on why shows are being canceled. The book states that networks should be focused on the quality of audience engagement and less on the quantity of viewers. However this is not what keeps a show on the air, such as American Idol. The "Corpse" section that talks about the hype of the show is one of the most important things in a show. So for those whose shows are getting canceled, it is most likely because of the amount of viewers, or has something to do with money.
