Other top downloads of 2013 include the photo and video-sharing service Snapchat. Craig Palli, an industry expert, said: "Snapchat went from being a niche app to achieving much more critical mass, so much so that Facebook was reportedly willing to spend billions of dollars to acquire the company." Mobile communications analyst Simon Khalaf believes 2014 could be the year when mobile apps seriously challenge the television industry. He said: "Every American spends $100-plus per month on a service that is not personalized and not mobile. It's an area that's ripe for disruption….Someone will come up with new content, maybe a new device, and more importantly a better business model." XYZ
