BABAR has started data taking in 1999 and has now accumulated nearly 100 fb-1 of data around the Upsilon(4S) resonance. The experimental environment and the status of the BABAR experiment will be described and the analysis strategy to extract CP asymmetries will be explained. The latest measurements of time-dependant CP asymmetries in B decays to charmonium final states, based on a sample of 88 million Upsilon(4S) decays to B meson pairs, will be explained in detail. These results, which clearly establish the presence of CP Violation in B meson decays and are in good agreement with the measurements from the Belle experiment, will be interpreted within the context of the CKM Unitarity Triangle. The results will also be compared with results from indirect measurements. Finally, we will discuss some prospects of future measurements with the BABAR experiment.
