SAN FRANCISCO: Facebook Inc launched a stripped down version of its popular Messenger app for emerging markets on Monday as it seeks to expand its international footprint. Messenger Lite, which uses less data and is designed to work in areas with slower internet connections, will roll out in Kenya, Tunisia, Malaysia, Sri Lanka and Venezuela. Facebook said it will expand to other countries in the coming months. Facebook has largely saturated Western markets, including North America and Europe, and has set its sights on developing countries, in part by rolling out “lite” versions of its main Facebook app and now Messenger, which have fewer capabilities than the main apps.
