  This paper discusses recent results and near-term prospects of the
long-baseline neutrino experiments MINOS, MINOS+, T2K and NOvA. The non-zero
value of the third neutrino mixing angle {\theta}13 allows experimental
analysis in a manner which explicitly exhibits appearance and disappearance
dependencies on additional parameters associated with mass-hierarchy, CP
violation, and any non-maximal {\theta}23. These current and near-future
experiments begin the era of precision accelerator long-baseline measurements
and lay the framework within which future experimental results will be
interpreted.
