Where do you get this impression? I've lived in France my whole life and most people I know try to avoid subtitles as much as possible. Most of the foreign TV contents are dubbed anyway, except on a few channels (Arte).
This may be less true for the new generation accustomed to watching subtitled TV shows on the internet, instead of waiting for a few years to get them in French on TV.
