  In this decade, the exploration of CP violation is governed by the B-meson
system, where non-leptonic decays play an outstanding role. To set the stage,
we have first a look at the main strategies to circumvent the calculation of
the relevant hadronic matrix elements in these studies, and discuss popular
avenues for physics beyond the Standard Model to enter the roadmap of
quark-flavour physics. We are then well prepared to analyze puzzles in the data
for B -> phi K and B -> pi K decays, and to discuss b -> d penguin processes,
which represent a new territory for the B-factory studies. Finally, we turn to
the physics potential of the Bs-meson system, which can be fully exploited at
the LHC.
