### Introduction  
Broadcasting plays a vital role in shaping public opinion, providing entertainment, and disseminating information.

These two systems cater to different objectives, funding structures, audiences, and operational frameworks.

### Definition of Commercial Broadcasting  
Commercial broadcasting refers to a media system funded by advertisements and driven by profits. It aims to maximize viewership and revenue by delivering content that appeals to the largest possible audience. Examples include private TV channels like NBC and Fox in the United States, and Zee TV or Sony Entertainment Television in India.

Examples of PSBs include the BBC (British Broadcasting Corporation) in the UK and Doordarshan in India.
