So we shouldnt add important information just because some people dont know what it means  Wouldnt it be simpler to explain what it means and why its important to their favorite TV show  since it is the most important factor to whether a show stays on the air or not demo ratings indicate what portion of adults  the segment of the population most desired by advertisers watch a particular episode  The higher the number the more a network can charge for advertising ergo the more successful a show is  There that wasnt too tough was it   Reporting irrelevant information like total viewers  many shows with large viewerships get cancelled if their demo ratings are too low ie below a  just because its easy to understand doesnt seem like a valid reason for listing some information and not others  Ratings are reported by every major news media even US Today reports the  rating so obviously many do know what it means   Not including the demo  ratings in an entry about a TV show is like listing baseball games without the score As for where to put it at one point the demo rating shared a box with total viewership in the episode listing  either put it back there or create a new box in the episode listing grid for the demo rating  Doesnt seem like a big deal to add it
