Who cares?

That’s the question I was asked time and time again when I told people that BBM was coming to Android and iOS. But it seems a lot of people care. In fact, when BBM finally made its cross-platform debut yesterday, the app was downloaded over 5 million times in just eight hours.

Twitter hopes to compete with instant messaging services like WhatsApp and Line with a new app that’s dedicated to direct messaging, AllThingsD reports. The company hopes the move will bring “the long-buried feature to the forefront” and place a new emphasis on its private messaging capabilities.

Samsung has today announced that its cross-platform ChatON messaging service now boasts over 100 million users across Android, BlackBerry, iOS, and Windows Phone. It’s taken just two years for the service to become more popular than BBM, once one of the biggest names in instant messaging, and it continues to grow at an impressive rate.

BlackBerry failed miserably in its attempt to bring BBM to Android and iOS last week, but the Canadian company hasn’t given up on making its popular messaging service available to all. In fact, it isn’t just targeting other mobile platforms, but it’s also planning to bring BBM to your desktop, too.

Disa.im is a new app on the Play Store, currently in alpha, that aims to bring a unified messaging inbox for all the various messaging services out there. Currently, the application only supports the traditional SMS and Whatsapp, but the developer is working hard on adding Facebook Messenger integration as well.
