Answer:
Option A.
Mass marketing; digital marketing
Step-by-step explanation:
Mass marketing refers to the various market strategies which are employed with the aim of selling to as many people as possible.
Digital marketing refers to the use of the internet, mobile devices, social media platforms, search engines, and other channels to reach consumers.
The problem with mass marketing is that the target audience is way to much. This makes marketing efforts seem generic, and most of the time, it is difficult to meet the paying point of customers this way.
Modern day technology has made it possible for customers to be targeted based on their persona, and given offers that meet their paying points, thus leading to more sales.
Thus, the explosive developments in communication technologies have left companies doing less mass marketing and more digital marketing.
