Twitter is a micro-blogging company that allows users to send short text updates to others. The site is used by people, including celebrities, government officials, and businesses.

Even though almost 10 million people visited the site in early 2009, the site had no strategy for monetizing the traffic. The case allows students to examine potential monetization strategies for Twitter.
