Mobile media usage is growing rapidly around the world. In the US, over 80 million mobile users now browse the internet or use apps on their phones, a 34% increase year-over-year. Growth is driven by new smartphone purchases around the holiday season, as consumers are more likely to use mobile media features on newer devices. However, mobile media engagement falls over time as the initial excitement of a new device recedes. Smartphone owners remain more engaged over the long run compared to non-smartphone owners. Latin America is also seeing rising mobile internet and social media usage, fueled by increasing smartphone adoption.
