8 + citations (prefer primary sources)
Please tailor the research done mainly to US and global industries as I live and study in the US

This research paper should start with looking at traditional direct marketing, how the use of database marketing enhanced direct marketing, and how it all evolved into today’s interactive marketing (engaging the consumer). Major bulk of the paper should be focused on interactive marketing and what the future holds, trends, etc. (Social Media, mobile, etc).
