vs other users of advertisement? Its not that it doesn&#x27;t &quot;work&quot; its that its an arms race. If your competitor does it, then you will lose if you don&#x27;t do it as well.<p>So, the size of your marketing department is more related to the size of your competitors department, than any actual effectiveness. Which is another way of reinforcing monopolistic consolidation. A large competitor likely can significantly outspend a smaller one with advertising dollars, which just goes to cement its position in the market.
