An increased TV audience refers to a larger number of viewers tuning in to a particular television program or channel. This can be measured by ratings, which track the number of households or individuals watching a show at a given time. A growth in TV audience can be attributed to various factors such as popular content, effective marketing, or a surge in interest for a particular event or topic. The term is often used to indicate the success and popularity of a TV program, as a larger audience can lead to higher advertising revenue and overall success for the network.
