In my country, Mexico; the most used were: Ole Georg Music, Network Music Ensemble, Sound Ideas, Parry Music, Focus Music, Music House, KPM and Megatrax. They were widely used in the 60's, 70's, 80's, 90's and from the year 2000 they have gradually been discontinued, so today they are hardly used anywhere. Now television, radio, film and streaming use their own compositions.
