Advertisements exist in numerous formats: traditional media including television commercials, radio spots, print ads in newspapers and magazines, and outdoor advertising like billboards. Digital ads include search ads, display ads, social media advertisements, video ads, and native advertising. Email marketing and influencer sponsorships also represent modern advertising approaches.

The 20th century saw mass advertising through radio and television, while the 21st century has transformed advertising through digital platforms and real-time targeting.

Platforms like Google, Facebook, and programmatic ad networks use data analytics and algorithms to serve ads to users based on demographics, interests, browsing behavior, and purchase history. This targeted approach improves ad relevance and efficiency.
