This is SBS publishing an article about a show which they broadcast, so this could be considered akin to 'sponsored content' (advertisement).

"The ideas of the ruling class are in every epoch the ruling ideas, i.e. the class which is the ruling material force of society, is at the same time its ruling intellectual force."
