Google Hangouts is an instant messaging and video chat platform developed by Google, which launched on May 15, 2013 during the keynote of its I/O development conference. It replaces three messaging products that Google had implemented concurrently within its services, including Talk, Google+ Messenger, and Hangouts, a video chat system present within Google+. Google has also stated that Hangouts is designed to be "the future" of its telephony product, Google Voice, and integrated some of the capabilities of Google Voice into Hangouts.^[1]

Prior to the launch of Hangouts, Google had maintained several similar, but technologically separate messaging services and platforms across its suite of products. These have included the enterprise-oriented Google Talk (based on the XMPP protocol), Google+ Messenger, and the Hangouts feature of Google+, which allows for group videoconferencing with up to 10 users at once. However, its increasingly fragmented and non-unified suite of messaging offerings was also facing growing competition from services such as Facebook Messenger, iMessage, and WhatsApp. A decision was made to scrap the existing Google Talk system and code a new messaging product through a collaboration with multiple development teams.^[2]

Following reports that the new service would be known as "Babel", the service officially launched as Hangouts during the Google I/O conference on May 15, 2013.^[2][3]

KakaoTalk (Hangul: 카카오톡) is a free mobile messenger application for smartphones with free text and free call features. It is available on iOS, Android, Bada OS, BlackBerry, Windows Phone, and PC.

KakaoTalk provides free call and text-messaging services. In addition, users can share diverse content and information from photos, videos, voice messages, and URL links to contact information. Both one-on-one chat and group chats are available over Wifi or 3G, and there are no limits to the number of friends who can join in group chat. one recent development is that users in group chats can perform free calls. Furthermore, if someone doesn't want to call in group chats, he or she can push the "ignore" button.

KakaoTalk automatically synchronizes with the user’s contact list and finds friends who are on the service. Users can also search friends by KakaoTalk ID without having to know each other's phone number. The KakaoTalk service also allows its users to export their messages and save them for future reference if the users so desire.^[1]
