Facebook's overall revenue growth of 52 percent blew past estimates. China only came up once on the call, but it was all investors needed to hear.
"We're also pleased with the growth we're seeing in emerging markets in countries like China, where businesses are advertising on Facebook and Instagram to reach people internationally," Chief Operating Officer Sheryl Sandberg said.
The stock soared 16 percent.
Neither Amazon.com nor Microsoft had much to say about China on their calls on Thursday, though Microsoft took a significant earnings hit due to the strength of the dollar. Alphabet reports results on Monday and shouldn't be terribly hurt by China since the Google search engine isn't available there.
