My Topic:
During marketing, SNS is a tool that marketers should consider.

What I hope to learn from this source:
I want to show current status in marketing(statistics that show how many people do SNS,especially in Facebook.

Notes:

Final Thoughts:

This research can support my confirmation part because we can see that SNS user is increased by geometric progression (Facebook is just one example of SNS, but only its number of users is amazing) so I can say that today's people are all connected to SNS(Even though one might not do SNS, his or her friends, families do SNS).
