It then began airing regularly under its more commonly known title from late 1964 to 1998, on ABC.  Since 2004, it has aired sporadically as a special program, now titled the "ABC Sunday Movie of the Week", though as of the 2011-12 television season, the only films in this timeslot were aired under the "Hallmark Hall of Fame" banner, which transferred to ABC in that season.

As a result of this, the Sunday Night Movie is now exclusively relegated to 2 special holiday movies, "The Sound of Music" every holiday season and "The Ten Commandments" every Easter.
