Tod Maffin of Inside the CBC reveals a memo to CBC employees countering this article:

• Layfield comes out swinging against ratings critic
  “These are bona fide share numbers for prime time, the most competitive and important hours on any TV network schedule. They are accurate, they are verifiable (if only some journalists took the time) and most important, they represent all of your hard work, which has paid off in achieving our best prime-time share results in five years.”

Guy Dixon of the Globe and Mail reports on CBC’s new system of rating shows:

• CBC-TV fine-tunes rating system: Unlike private broadcasters who gauge shows only in terms of revenue, audience numbers and costs, CBC will try to measure ‘public value’
  “Known as PARC and detailed in a recent memo from CBC-TV executive vice-president Richard Stursberg to staff, the system gives all CBC shows a target number for their public value (P), expected audience (A), estimated revenues (R) and costs (C). Public value is measured two ways: Shows are given a number on a 1-to-5 scale for their relative distinctiveness, and then audiences are surveyed to measure the shows’ quality.”
