As this difference increases, so does the Cpm. And as this index becomes larger, the Cpm gets smaller. If the difference between the data and the target is small, so too is the sigma. And as this sigma gets smaller, the Cpm index becomes larger. The higher the Cpm index, the better the process, as shown in the diagrams below.
The third season was released on June 25, 2013 and the fourth season was released on November 12, 2013. Originally, reruns of Mad TV aired as 30-minute reruns on local TV stations, often under the banner The Best of Mad TV . The cable channel TNN (now Spike TV) aired the first six seasons of Mad TV from 1999 to 2001.
It has influenced generations of British television professionals, many of whom grew up watching the series. The programme originally ran from 1963 to 1989. There was an unsuccessful attempt to revive regular production in 1996 with a backdoor pilot, in the form of a television film titled Doctor Who. The programme was relaunched in 2005, and since then has been produced in-house by BBC Wales in Cardiff.
