  Charm physics has attracted increased attention after first evidence for
charm mixing was observed in 2007. The level of attention has risen sharply
after LHCb reported first evidence for CP violation in the charm sector.
Neither mixing nor CP violation have been established by a single unambiguous
measurement to date. This review covers the status of mixing and CP violation
measurements and comments on the challenges on the road ahead, both on the
experimental and theoretical side, and on ways to tackle them.
