Net even de finiancial statement opgezocht. Het staat er een beetje onduidelijk, maar volgens mij hebben ze toch behoorlijk wat advertisement inkomsten. 89% van $422M
<quote> Although we do not generate revenue directly from users or platform partners, we benefit from network effects where more activity on Twitter results in the creation and distribution of more content, which attracts more users, platform partners and advertisers, resulting in a virtuous cycle of value creation.
Mobile has become the primary driver of our business. Our mobile products are critical to the value we create for our users, and they enable our users to create, distribute and discover content in the moment and on-the-go. The 140 character constraint of a Tweet emanates from our origins as an SMS-based messaging system, and we leverage this simplicity to develop products that seamlessly bridge our user experience across all devices. In the three months ended September 30, 2013, 76% of our average MAUs accessed Twitter from a mobile device, including mobile phones and tablets, and over 70% of our advertising revenue was generated from mobile devices. We expect that the proportion of active users on, and advertising revenue generated from, mobile devices, will continue to grow in the near term.
We have experienced rapid growth in our revenue in recent periods. From 2011 to 2012, revenue increased by 198% to $316.9 million, net loss decreased by 38% to $79.4 million and Adjusted EBITDA increased by 149% to $21.2 million. From the nine months ended September 30, 2012 to the nine months ended September 30, 2013, revenue increased by 106% to $422.2 million, net loss increased by 89% to $133.9 million and Adjusted EBITDA increased by $27.1 million to $30.7 million. For information on how we define and calculate Adjusted EBITDA, and a reconciliation of net loss to Adjusted EBITDA, see the section titled “—Summary Consolidated Financial and Other Data—Non-GAAP Financial Measures.”
We generate the substantial majority of our revenue from advertising. The loss of advertising revenue could harm our business.
The substantial majority of our revenue is currently generated from third parties advertising on Twitter. We generated 85% and 89% of our revenue from advertising in 2012 and the nine months ended September 30, 2013, respectively. We generate substantially all of our advertising revenue through the sale of our three Promoted Products: Promoted Tweets, Promoted Accounts and Promoted Trends. As is common in the industry, our advertisers do not have long-term advertising commitments with us. In addition, many of our advertisers purchase our advertising services through one of several large advertising agency holding companies. Advertising agencies and potential new advertisers may view our Promoted Products as experimental and unproven, and we may need to devote additional time and resources to educate them about our products and services.
