Almost ironically, the instant messaging services that burst in popularity on mobile devices are now trying to stake a claim on desktops as well. Viber has long had a desktop version of its app. WhatsApp now has a web version that supports different browsers. Now LINE is adding to that list, but in a sort of different way. Yes, it's still somewhat web-based but it is going for something even more specific. LINE is now making available a new PC version, this time as a Google Chrome extension.
