Final answer:
Marketing data can be obtained from information subsidies, interviews with experts, and promotional materials.
Explanation:
Marketing data can be obtained from information subsidies created by organizations and institutions, such as news releases, media kits, and privately-funded research studies. These sources are often used to promote the needs and interests of the organizations.
Another valuable but often neglected source of free marketing data is interviews with experts in specific fields, industry workers, or representatives from organizations. Interviews provide firsthand information that can be crucial for marketing strategies.
Furthermore, promotional materials like product catalogs, news releases, and enthusiast magazines from private-sector institutions are rich sources of persuasive content aimed at customers and journalists.
