CP Violation in the B System

Strategies for extracting CKM phases from non-leptonic $B$ decays are reviewed briefly. Both general aspects and some recent developments including CP-violating asymmetries, the $B_s$ system in light of a possible width difference $\Delta\Gamma_s$, and triangle relations among $B$ decay amplitudes are discussed. The role of electroweak penguins in these strategies is illustrated briefly.
