I hate to say it, but the easiest example is using videos/movies. Lets say people in a house watch more and more streamed video over time. They start out watching one movie per week. After a few weeks they start watching two movies per week. The next month they watch three movies each week. As long as they aren't trying to watch them at the same time, they are transferring once, twice and then three times the data volume each month, without using or requiring any more bandwidth. Its only when the household starts trying to do multiple things *all at the same time* that they might start seeing congestion and looking to upgrade to more bandwidth. In this way, averaged over the whole population, data volume consumed can grow considerably each month even though actual bandwidth doesn't need to grow nearly as much.
