The experimental status of the polarization measurements in B to charmless
vector-vector decays by both the Belle and Babar experiments is reviewed. The
results obtained in related vector-tensor, axial vector-vector, and axial
vector-axial vector modes are also given.Comment: 6 pages, 5 figures, Proceedings of CKM2010, the 6th International
