Digital marketing became more sophisticated in the 2000s and the 2010s, when[18][19] the proliferation of devices' capable of accessing digital media led to sudden growth.[20] Statistics produced in 2012 and 2013 showed that digital marketing was still growing.[21][22] With the development of social media in the 2000s, such as LinkedIn, Facebook, YouTube and Twitter, consumers became highly dependent on digital electronics in daily lives. Therefore, they expected a seamless user experience across different channels for searching product's information. The change of customer behavior improved the diversification of marketing technology.[23]

In the 2000s, with increasing numbers of Internet users and the birth of iPhone, customers began searching products and making decisions about their needs online first, instead of consulting a salesperson, which created a new problem for the marketing department of a company.[15] In addition, a survey in 2000 in the United Kingdom found that most retailers had not registered their own domain address.[16] These problems encouraged marketers to find new ways to integrate digital technology into market development.
