After about 10 years of growing interest for Generalized Parton Distributions come the first results from dedicated experiments, using
the golden Deeply Virtual Compton Scattering process. After a short introduction, we will explain the experimental methodology and
show results of the Hall A E00-110 experiment, which aimed at measuring helicity-dependent photon electroproduction cross sections.
We will enphasize how this experiment provided the first stringent tests of the scaling property of this process, allowing for the
first time a model-independent extraction of a linear combination of Generalized Parton Distributions.
We will also describe the Hall B E01-113 experiment which
measured the photon electroproduction beam spin asymmetry over a wide kinematical range. The summary will include an outlook on
the next generation of experiments which are already planned at Jefferson Lab at 6 GeV, but also after the planned 12 GeV upgrade.
