Broadcasting in the era of plenty: the case for national public television in Canada
Bibliographic record
Abstract
Public service broadcasting (PSB) plays a unique role in media landscapes across the world.This thesis argues that, while the broadcasting landscape in Canada has changed as new technologies have developed and the overall environment in which PSB operates has evolved, there is still a role for it to play in the country.With a focus on national public television in Canada, a timeline of the evolution of PSB in the country as it appears in official policy documents is provided.After establishing a timeline of development, this thesis discusses national public television in the 21 st century through an analysis of interventions submitted to the Canadian Radio-television and Telecommunications Commission for the Canadian Broadcasting Corporation's (CBC) 2013 licence renewals.It is demonstrated through a content analysis of the nearly 6,000 English-language interventions submitted, that Canadians support the continued existence of the CBC.Suggestions for future research are also discussed.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
