The phrase "to attract new audiences" means to bring in or gain a larger number of people who are interested in what is being presented, performed, or sold. It refers to efforts made to reach out and engage with different groups of individuals, in order to expand the range of people who are aware of and participate in whatever it is that is being offered. This could be through marketing campaigns, changes in content or presentation, or other strategies aimed at broadening the appeal of a product, service, or event. The goal is to increase the number of people who become fans, customers, or supporters, and ultimately help sustain or grow the business, organization, or movement involved.
