In Chicago author–date referencing, you usually give an author’s surname and a year of publication in in-text citations. However, a radio programme doesn’t have an author as such. Instead, the name you use to cite a radio broadcast will refer to the creator or contributor involved in the programme who is most relevant to your writing.
Usually, it will be the surname of the presenter, writer or producer. It all depends on which creator or contributor is most pertinent to your work or argument. For example, if we were to cite a radio documentary presented by Ian Hislop, we might choose to cite his surname and the year of broadcast:
Much of the story told is based on records from the Venerable Bede (Hislop, 2021).
But you can cite other contributors if relevant. For an interview, for example, you would usually cite the interviewee’s surname, not the interviewer’s surname. And if you were quoting the interview directly, you may need to include a timestamp to indicate where the quote occurs in the broadcast. For example:
In the interview, Sharma (2021, 00:23:18) says, ‘algorithms are starting to be used in the criminal justice system’ as well as in many other areas of daily life.
Here, we’re quoting something Kriti Sharma says in an interview, so we cite his surname as the contributor most pertinent to what we are saying in the text. And since we’re quoting a line from 23 minutes and 18 seconds into the broadcast, we include a timestamp in the citation (like we would with page numbers for a book).
Radio Broadcasts in a Chicago Reference List
In the reference list at the end of your document, you will need to give full details of every source cited in the main text. For a radio programme, the format is:

Surname, First Name, role. Year. ‘Title of Broadcast’. Name of Series. Date and station of first airing. URL (if accessible online).
The key point here is that the surname listed at the start of the reference list entry should match the name used in citations. This ensures that readers can find the relevant entry in the reference list based on the information in the citation.
For instance, references for the above examples would look like this:
Hislop, Ian, presenter. 2021. ‘Northumbria – The Great Divide’. This Union: The Ghost Kingdoms of England. Aired 9 August 2021, on BBC Radio 4. https://www.bbc.co.uk/programmes/m000ykph.
Sharma, Kriti, interviewee. 2021. ‘Tech for Good: Marcus Smith speaks to Kriti Sharma’. One to One. Aired 11 May 2021, on BBC Radio 4. https://www.bbc.co.uk/programmes/m000vwqk.
Note, too, that the second and subsequent lines for entries in a Chicago reference list entry require a half-inch (1.27cm) hanging indent.
