It depends on:
* The station's policies: Some stations have strict policies against using full names, especially for privacy reasons. Others are more relaxed, especially for public figures or with explicit consent.
* The context: Using a full name in a news report or interview is often acceptable, especially if it's relevant to the story. Using someone's full name in a humorous or gossipy way, however, might be considered inappropriate.
* The person's privacy: It's important to consider the person's wishes and privacy rights. If someone has a valid reason to not have their full name used, it's best to respect that.
* The nature of the show: Some shows are more informal and allow for more personal details, while others are more serious and stick to professional boundaries.
General recommendations:
* Always err on the side of caution: If you're unsure, it's always best to ask the station's policy or the person involved.
* Get consent: Before using someone's full name, especially if it's not a public figure, it's good practice to get their consent.
* Be mindful of privacy: Think about the potential impact on the person whose name you're using. Could using their full name put them in danger or harm their privacy?
In short, there is no one-size-fits-all answer. Using someone's full name on radio requires careful consideration of the context, policies, and the person's privacy.
