Notes:

1> The main uses of television are depending on age …. here you should use the present simple: The main uses of television depends on age … (because this is an opinion/fact. It’s not about time)

Suggestions:

Another way to say low/high intellectual level – less/more cultured/educated. Low intellectual level – ignorant, uneducated, unread, uncultivated
