Twitter announced the Periscope Producer API, which will give third-party apps the ability to authenticate Periscope accounts and let people push live video from just about anywhere. The idea is to make it easier to share video from just about any device and reduce pain points for end users.
Twitter Kit 3 was introduced as a standalone SDK earlier this year. Originally limited to Android and iOS, Twitter has expanded support to Unity. Whether its login authorization, in-game Tweets, or sharing, Twitter Kit for Unity might change the gaming landscape through more social capability.
