Paid Media and Content scale differently. That's the main reason why companies jump to invest in paid media while hesitating to invest in content.
One has a low barrier to entry (money). The other has a high barrier to entry (time, effort and creativity).
Building the content engine for a company takes patience and playing the long game.
Content is also how you scale paid media faster because all kinds of possibilities open up beyond the usual campaigns that everyone else in your market is competing for.
