Messaging service Line introduced a unique new feature with the latest update to its mobile and desktop apps: the ability to conference call with up to 200 people. Skype, for comparison, supports only 25-person chats. The feature is now available on iOS, Android and Windows desktop with Mac support coming soon. The feature is free and can be initiated from both group and multi-person chats. Interestingly, the conference call feature will first be released outside of Asia -- sort of as an informal beta test before Line introduces it to its core markets of Japan, Thailand, Taiwan and Indonesia.
