AI Analysis: Advertising and related services, sales by type of client

Executive Summary

Canadian advertising and related services sales remain overwhelmingly business-to-business, with sales to businesses averaging 81.3% of revenue across 2013–2024, though that share declined notably from 83.4% to 75.3% over the period. Export sales have grown as an offsetting force, showing a strong inverse correlation of -0.915 with domestic business sales, suggesting a structural shift in how Canadian advertising firms source their revenue. The dataset, covering 8 NAICS sub-sectors and 5 client types annually, reveals a highly skewed distribution where a small number of dominant categories mask consistently low sales to individuals (averaging just 1.5%) and governments (averaging 6.8%).

Key Findings

• Sales to businesses are the dominant client segment, averaging 81.3% of advertising services revenue across all NAICS categories from 2013 to 2024, confirming the industry is overwhelmingly B2B.
• Business sales declined by approximately 8 percentage points — from 83.4% in 2013 to 75.3% in 2024 — signaling a gradual but meaningful diversification of the Canadian advertising client base.
• Export sales (sales outside Canada) show a very strong inverse correlation of -0.915 with domestic business sales, suggesting that growth in export revenue has come at the expense of domestic business market share.
• Sales to individuals and households are the smallest client segment, averaging only 1.5% (range: 1.0%–3.1%) over the full 12-year period, underscoring the near-absence of consumer-facing advertising service revenue.
• Sales to governments, non-profits, and public institutions averaged just 6.8% and show a moderate negative correlation (-0.558) with business sales, indicating these segments also tend to move in opposite directions over time.
• The overall dataset is heavily right-skewed, with a mean of 41.67% versus a median of 13.30% and a standard deviation of 42.35%, driven structurally by the 'Total sales to all clients' category always recording 100%.
• Outlier detection flagged 4 anomalous data points across the 2013–2024 period, potentially linked to economic disruptions such as COVID-19 in 2020 or other structural shifts in advertising spending patterns.
