They are typically used in television productions where they can be held off-camera and are unseen by the audience.  Cue cards are still currently being used on many late night talk shows including "The Tonight Show Starring Jimmy Fallon", "Late Night with Seth Meyers" and "Conan" as well as variety and sketch comedy shows like "Saturday Night Live" due to the practice of last minute script changes.  Many other TV shows, including game and reality shows, still use cue cards due to their mobility, as a teleprompter only allows the actor or broadcaster to look directly into the camera.
