The messaging application WhatsApp said it would begin offering business accounts for the first time, a step that can make money for its corporate parent, Facebook Inc. The accounts are aimed at businesses that heavily use WhatsApp messages. WhatsApp is planning to charge businesses in some form in the future, but gave no details on when that would happen or what the future business services would look like. Facebook acquired WhatsApp in 2014 for $19 billion, attracted by the size of its user base. WhatsApp used to charge a $1 annual subscription fee but dropped it in 2016, leaving the service without a source of revenue. The announcement comes after Mark Zuckerberg said on Friday last week Facebook is making a “major change” to its News Feed. Facebook stock lost momentum as economist believe it is possible that these changes will result in lower ad load in the News Feed, hence lower revenue.
