Description
Starting from the discovery of X(3872) in 2003, the charm spectroscopy
revealed a lot of surprises. Every year brings new states and new puzzles.
We shall briefly discuss the old experimental results and concentrate on
the recent news on the charged charmonium-like states, new results on
X(3872), 1-- states observed in e+e- annihilation via initial state
radiation, three states X,Y,Z(3940) with about the same mass but different
properties and also discuss the first news from the bottomonium sector.
