In May 2014, Instagram had over 200 million users. The user engagement rate of Instagram was 15 times higher than of Facebook and 25 times higher than that of Twitter. According to Scott Galloway, the founder of L2 and a professor of marketing at New York University's Stern School of Business, latest studies estimate that 93% of prestige brands have an active presence on Instagram and include it in their marketing mix. When it comes to brands and businesses, Instagram's goal is to help companies to reach their respective audiences through captivating imagery in a rich, visual environment. Moreover, Instagram provides a platform where user and company can communicate publicly and directly, making itself an ideal platform for companies to connect with their current and potential customers.
Twitter allows companies to promote their products in short messages known as tweets limited to 140 characters which appear on followers' Home timelines. Tweets can contain text, Hashtag, photo, video, Animated GIF, Emoji, or links to the product's website and other social media profiles, etc. Twitter is also used by companies to provide customer service. Some companies make support available 24/7 and answer promptly, thus improving brand loyalty and appreciation.
In the 1990s, the term Digital Marketing was first coined,. With the debut of server/client architecture and the popularity of personal computers, the Customer Relationship Management (CRM) applications became a significant part of marketing technology. Fierce competition forced vendors to include more service into their software, for example, marketing, sales and service applications. Marketers were also able to own huge online customer data by eCRM software after the Internet was born. Companies could update the data of customer needs and obtain the priorities of their experience. This led to the first clickable banner ad being going live in 1994, which was the "You Will" campaign by AT&T and over the first four months of it going live, 44% of all people who saw it clicked on the ad.
