Recent results for the asymptotic behavior of
fermion scattering amplitudes in the Sudakov
limit are discussed including next-to-leading logarithmic (NLL)
and NNLL corrections.
These are used for the analysis of the
dominant electroweak corrections to the fermion-antifermion pair
production in $e^+e^-$ annihilation at high energy.
The importance of angular dependent as well as subleading terms is emphasized.
