A "call-in show" is a type of radio or television program where listeners or viewers are invited to call the show and participate in discussions with the host and other guests. There are several synonyms for this term, including "phone-in show," "dial-in show," "talkback show," or "interactive show." These programs are often structured around a particular topic, such as politics, sports, entertainment, or current events, and provide a platform for people to share their opinions and engage in debate with others. Call-in shows are an exciting and dynamic way to connect with a wider audience and foster meaningful dialogue on important topics.
