With more than 1 billion smartphones in consumers' pockets at the beginning of 2013, mobile is driving a second Internet revolution that's even more profound than the first one.

This fourth annual mobile trends report revisits our 2013 mobile trends, elaborates on how they will continue to evolve in 2013, and highlights new mobile trends that we expect to see this year. New to this year's report is a list of the over-hyped topics that we believe will fail to provide real business value in the short term.
