This article misses the origin of the term 'growth hacker'. There are two primary shifts that got us here: 1. Marketing moving from being an external function to an internal function that is embedded in the product. Thus product design, product development, and product management skills are becoming very important skills to possess as part of a marketing function. 2. As marketing channels shift from being largely immeasurable to measurable at a very detailed level the marketing function demands more understanding of data and statistics. Hence the term "growth hacker". Someone with product design, product development, and product management skills who also has a solid understanding of data and statistics, then leverages these skills to direct marketing efforts whether internal (product driven) or external (advertising/content driven).
