Following Facebook’s $1 billion acquisition of popular photo-sharing service Instagram, the company is reportedly now considering another billion-dollar deal. According to Israel-based newspaper Calcalist, Facebook is in the late stages of acquisition talks with Israeli social navigation service Waze and the deal could be worth between $800 million and $1 billion. The talks reportedly began six months ago and due diligence is now underway. TechCrunch previously reported that Apple was in talks to acquire Waze, but then later debunked its own report in a subsequent post.
