Evolution of Online Advertising:

Online advertising has evolved significantly over the years, adapting to the changing technology and consumer behavior. Initially, banner ads were the primary form of online advertising, but as the internet matured, new and more sophisticated advertising formats emerged. Today, online advertising encompasses a wide range of formats, including display ads, search engine marketing (SEM), social media advertising, video ads, native ads, and more.

Advantages of Online Advertising:

2. Privacy and Data Protection: Online advertising raises concerns about user privacy and data protection, leading to increased scrutiny and regulations on data collection and usage.
