Twitter has finally made its S-1 filing publicly available to all investors. Thanks to several strong quarters from Facebook (NASDAQ:FB) and LinkedIn (NYSE:LNKD), social media is hot again and Twitter's timing couldn't be better. Investors are anxious to get a piece of the company, but now financial data is available for assessing its prospects.

There are now 218 million monthly active users on Twitter's popular service, with nearly 80% of these users located internationally. Much like Facebook, Twitter has a much harder time monetizing these international users, with 75% of sales being generated in the U.S.

Twitter has also been spending more on research and development compared to its larger rivals like Facebook and LinkedIn. This could potentially be part of its broader goals to expand internationally.

In this segment from Tech Teardown, Erin Kennedy discusses Twitter's S-1 filing with Jamal Carnette and Evan Niu, CFA.
