I'd like to ask about prepositions in the following sentence:
The law establishes that rebroadcasting of TV- and radio programs of foreign mass media should not exceed 20 per cents of the total volume of programs broadcasted on TV and radio.
Are 'of' and 'on' the correct preposition?
The law establishes that rebroadcasting of foreign TV and radio programmes should not exceed 20 per cent of the total volume of programmes broadcast on TV and radio.
TV and radio 'programmes' is Brit. Eng.
'programs' is Amer. Eng.
computer programs is both Brit, and Amer.
