The last few years have seen a shift in the aims of long baseline (LBL) neutrino oscillation experiments. Only a few year ago all experiments were trying to establish, if the last unmeasured mixing angle Theta13 was non-zero and thus allowing for CP violation in the neutrino sector. This changed, when LBL experiments like MINOS and T2K found evidence for muon to electron neutrino transitions and reactor experiments like Daya Bay, Reno and Double Chooz found evidence of the suppression of anti-electron neutrinos on baselines of the order of 2 km. Both these measurements clearly pointed to non-zero Theta13. In the following year, this angle went from totally unknown to the best measured mixing angle. Consequently, the aim of the LBL experiments has now changed. The aim is now to start to get a handle on the possibility of CP violation in the neutrino sector as well as measuring the mass hierarchy. The seminar will give a short review of the current status of the field and review of where the future might lead us.
