After the detection of the giant planet HR 8799 e with VLTI /GRAVITY and the characterization of the atmosphere of beta Pictoris b two years ago, it became apparent that long-baseline interferometry could play a major role in the characterization of giant planets. The ExoGRAVITY Large Program was granted 14 nights on the 4 UTs of the VLT , with the aim of observing all the directly imaged planets. We are now half-way through the program, and a number of exciting results have already came out: from the characterization of the HR8799 system to the direct detection of the radial-velocity planet beta Pic c, and the measurement of its mass through its effect on the orbit of its sister planet beta Pic b. I will give a general overview of the program: the science goals, the instrument, the observing strategy, etc. I will also dive into some of the most exciting results obtained so far.
