NEW YORK -- Facebook's stock gained the most in a single day Wednesday since it began trading in May, a good sign for the social media company.  

 

Facebook also gave details for the first time on how much money it made from mobile ads. This has been a concern since before its IPO. Although the majority of the 1 billion people who use Facebook each month now access it using a mobile device, the eight-year-old company was created in the age of desktop computers, for Web pages. Facebook now calls itself a "mobile-first" company, but it only started showing mobile ads earlier this year.
