WhatsApp adds Telegram-like channels
WhatsApp added an option to have only admins to send messages in group chats. This could be useful for people and companies that use WhatsApp as a way to send mass updates, and to cut down on noise and clutter. In fact it's an alternative for Telegram's channels, where only administrators can broadcast messages. This format is suitable for corporate micro-blogs to deliver company news, discount-offers or announcements to large number of customers.
WhatsApp alternatives are: Viber, Line, ICQ, BBM, Skype, Telegram, Google Hangouts, WeChat, Kik, Facebook Messenger
