When 78 RPM production ended does indeed vary by country. Here is an overview created by various members of 78-L, with some additional notes of my own. No doubt there are errors!
1958: major USA labels end production of 78s. However, Chess Records issued 78s until 1960, as did some of the four or six-selection per disk companies (e.g., Value Top Tunes), and there were some children’s 78 RPM records issued as late as 1964-65 (e.g., Disney Little Gem records).
1958 last 78 rpm on major Swedish labels, although some children’s 78 RPM records are issued as late as 1961.
