To be announced
Template:Redirect4 To be announced and To be determined (often abbreviated as TBA and TBD, respectively) are placeholder terms used very broadly to indicate that although something is scheduled or anticipated to happen, a particular aspect of that thing remains to be arranged. Although the phrases are often used interchangeably, "to be announced is subtly different from "to be determined" in that the aspect so designated may have already been "determined", but is not yet suitable for public announcement. Other similar phrases sometimes used to convey the same meaning, and using the same abbreviations, include To be ascertained, To be arranged, To be advised, and To be decided.
History
Use of the abbreviation, "TBA", is formally reported in a reference work at least as early as 1955,[1] and "TBD" is similarly reported as early as 1967.[2]
Examples
These various placeholder terms are often used to indicate to the public that a vacant position in a lineup of speakers, musicians, or other performers remains to be filled. The terms also frequently indicate that a creative work, such as an album or film, is forthcoming but that the date of release is not yet known. If the forthcoming project is not yet named, these placeholders may be used to indicate that the name has not yet been selected, although the project may also be designated as "untitled" pending that determination.
