Joe Flint wrote about TV executives manipulating advertizers:

• During Memorial Day weekend NBC seemingly had a typo in its lineup. Instead of watching “NBC Nightly News” people watched “NBC Nitely News”.
• It was intentional. By having a typo Nielsen, an automated ratings calculation system, assumed it was a new show, and didn’t count the lower Memorial Day weekend ratings as part of the show’s overall ratings.
• This helped NBC look like it was rated higher than it was, and allowed it to charge advertizers higher rates.
• NBC did this 14 times during the 2017-2017 TV season. CBC did it 12 times and ABC did it seven times.
• Executives have also tried to trick the system into thinking that a second airing of a program later in the evening should add to the viewer tally of the initial showing.
• And CBC successfully manipulated the system to deceptively indicate that “Bull” was the most watched new show of the season.
• Ad industry executives are understandably upset they’re being misled about how many people are actually seeing their ads.
