Since the advent of smartphones, robust data growth has been the bedrock of the telecommunications industry. Mobile-data traffic has exploded, propelled by increased mobile adoption, growth in smartphone penetration, larger phone screens, and the proliferation of video consumption. While growth slowed after the initial boom, it stabilized at 70 to 100 percent per year throughout most of the early 2010s.
