The phrase "broader audience" refers to a larger group or range of people, as opposed to a smaller or more specific group. It can be used in various contexts such as marketing, where reaching a broader audience is essential for increasing sales and expanding the customer base; or when discussing information dissemination, where making it accessible to a broader audience ensures that knowledge reaches more people. In essence, "broader audience" means going beyond niche groups and targeting a larger segment of society with one's products, services, ideas, or messages.
