What are the observed n to support that a decline in audiovisual investments is the direct trigger for streaming quotas in Australia? A simple temporal correlation is not a proven causal mechanism without a more robust dataset.
To establish such a causal link, a quantifiable threshold would be needed to demonstrate that beyond a certain percentage of decline, regulatory intervention is unavoidable and statistically proven.
Without precise measurements and a comparative sampling with other jurisdictions, this conclusion remains a hypothesis.
For example, the introduction of similar quotas in France for audiovisual media services was not conditioned by a drop in investment but by a political will to support local creation, regardless of macroeconomic conditions.
