Collider produced black holes are the most exciting prediction from models with large extra dimensions. These black holes exist in an extreme region, in which gravity meets quantum field theory, particle physics, and thermodynamics. An investigation of the formation and decay processes can therefore provide us with important insights about the underlying theory and open a window to the understanding of Physics at the Planck scale. In my talk, I will focus on observable effects of the black hole event. The production and the evaporation of TeV-scale black holes yields distinct signatures that have been examined closely during the last years, with analytical approaches as well as by use of numerical simulations. I will present new results for the LHC, which take into account that, instead of a final decay, a black hole remnant can be left. I will mention theoretical uncertainties, open questions and what knowledge we could extract from the observation of such a black hole event.
