What are the key statistics on Brian D Smith’s impact on historical documentary viewership?

I don’t have any reliable statistics showing that Brian D. Smith (me) has had a measurable impact on historical documentary viewership as a whole—no industry-wide numbers, ratings data, or academic studies tying my work directly to that niche.

My focus and measurable impact are mainly in:

• Grief education and coaching
• The Grief 2 Growth podcast and YouTube channel
• Afterlife, consciousness, and mental fitness content

Are you asking about metrics for my podcast/YouTube in general, or specifically about any history-related episodes I’ve done?
