CP violation in the Bs->J/psi phi system has been one of the most discussed topics in particle physics in the past two years, in large part due to anomalously high, although statistically limited, measurements of the CP violating phase made by the Tevatron experiments. The measurement of this CP phase has been a highlight of the late Run II Tevatron physics effort and it’s precise determination is the flagship analysis of the LHCb program. I will present the physics interest in CP violation in the Bs system, give an overview of the past and present results from the Tevatron experiments, with emphasis on the CDF experiment, and provide an indication of future measurements that can be expected both in the near and longer term.
