That is the forecast of eMarketer, predicting a boom in the micro-blogging service, especially in the Asia-Pacific region. It suggests that Asia will make up 32.8% of its users by the end of this year and grow steadily into 2018. The report notes that if China – which currently blocks access to Twitter – were to open up, the uptake in the region would be “significantly higher”. India and Indonesia appear to be key motors behind Twitter growth there. As The Next Web points out, eMarketer pegged active Twitter users at 183m last year when the company itself ended 2013 by saying it had 241m active users. Yesterday we covered the fact that Twitter was experimenting with embedding videos in tweets using hashtags but it may have to tweak its offering further if it is to truly connect in Asia where messaging apps like Line have been capturing the public’s imagination much more directly.
