Ah, I see, I didn't know that you weren't American. This is mostly an issue with broadcast shows; streamers just either release all episodes at once or they and cable networks show them weekly without breaks. But several cable shows and streaming shows will split their seasons in half and show the second half later. Of course, depending on where you live, many foreign shows are only 6 episodes long (like the UK) so repeats aren't an issue. In the old days, broadcast shows had many more episodes to fill the regular TV season and repeats were mostly relegated to the Summer
