Facebook has a problem: to exist, it needs to serve ads to users - the more with video, the better.<br />Facebook is launching a new lightweight type of ad on Thursday that uses a slideshow of up to seven high-resolution images that fade or flip into one another in a sequence to mimic the experience of a video without the taxing data usage.<br />The company is hoping that the more attractive advertising options for spotty connections will allow smaller local businesses around the world to buy more cost-effective ads and entice big multinational companies to tailor more of their ads to the developing world.<br />The move is part of Facebook's first steps towards better selling things to the millions of new users it brought online with tools like the bare-bones Internet.org and Facebook Lite .
