It simply means films that were never shown in theaters. A lot of films are made with the intention of releasing them in theaters, but turn out to be too bad and/or not popular enough and are therefore just shown on a television channel. Some films are made from the start as intended for TV-only broadcasts as well.

If the film was actually released in Cineams for even a brief period of time then it should simply be listed as "Movie". If it never made it to the big screen then it's a "Movie, Made for TV".
