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.  However, in 2014, The Hallmark Hall of Fame moved exclusively to cable on the Hallmark Channel, and as a result, said program is no longer on broadcast television in any form (including ABC) for good.  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.
