Media companies make a significant portion of their revenue from advertising. This can include television and radio broadcasters, print and online news outlets, and social media platforms.

Television and radio broadcasters typically make the majority of their revenue from advertising. For example, in the United States, the top four broadcast networks (ABC, CBS, Fox, and NBC) generated a combined $18.1 billion in advertising revenue in 2019. This accounted for the majority of their overall revenue, with the remainder coming from sources such as subscriptions and syndication fees.

Print media, such as newspapers and magazines, also rely heavily on advertising revenue. In 2019, print advertising revenue in the United States declined to $11.4 billion, down from a peak of $67.8 billion in 2000. Despite this decline, advertising is still a major source of revenue for print media, particularly for larger publications.

Online news outlets also make a significant portion of their revenue from advertising. In 2019, digital advertising revenue in the United States reached $129.3 billion, with a large portion of this going to news websites. However, the rise of ad blockers and the increasing use of ad-free subscription models has led to a decline in advertising revenue for some online news outlets.

Social media platforms, such as Facebook and Google, also make a significant portion of their revenue from advertising. In 2019, Facebook generated $69.7 billion in advertising revenue, while Google generated $134.8 billion. These platforms use targeted advertising to show users ads that are relevant to their interests, leading to higher engagement and ad revenue.

Overall, advertising is a major source of revenue for media companies, with television and radio broadcasters, print media, online news outlets, and social media platforms all relying on it to varying degrees.
