Facebook-owned messaging service WhatsApp is moving to reestablish its revenue stream by allowing businesses to message users.
Whatsapp used examples of a users bank notifying them about a potentially fraudulent transaction, or getting notified by an airline about a delayed flight as how the service could be used by businesses.

WhatsApp – which was acquired by social media giant Facebook in 2014 for $22bn (£16bn) – did away with its yearly $1 charge in January this year, removing its only source of revenue.
In a blog post the company wrote:
We want to explore ways for you to communicate with businesses that matter to you too, while still giving you an experience without third-party banner ads and spam.
Whether it's hearing from your bank about a potentially fraudulent transaction, or getting notified by an airline about a delayed flight, many of us get this information elsewhere, including in text messages and phone calls.
The messaging company has insisted however it will not not display adverts in the app – which is the way Facebook makes the majority of its money.
Other messaging apps – such as China's WeChat have already begun experimenting with business-to-consumer messages and many businesses have started asking their customers to add them on WhatsApp so they can send marketing and promotions directly.
Facebook Messenger, which is WhatsApp's main competitor outside of China, has been encouraging companies to build chat bots that use an artificial intelligence to communicate with users.
As part of the changes announced today WhatsApp plans to share its users’ phone numbers with Facebook, the first time the two services have shared data.
Facebook will receive more data about its users and allow it to do things like suggest phone contacts as Facebook friends.
WhatsApp reiterated the contents of messages – including words and images – cannot be read by the company as they are end-to-end encrypted, but it does have things like phone numbers and information about users' phones.
The move could spark concerns over privacy, with many users choosing to use WhatsApp because of its perceived security.
