Online businesses are more likely to use online advertising. I’ve been saying this forever, and here’s further proof from Double-Click and Nielsen.
Sectors that spend more than ten percent of their advertising budgets online included employment services (41 percent of $41 million in ad spending), media companies (15.5 percent of $479 million), retailing (15 percent of $3 billion), and travel 12 percent of their $788 million).
Categories that depend on branding, rather than online selling–such as pharmaceuticals, consumer packaged goods, and automobiles–are not spending much of their ad budgets online.
