Time-dependent density-functional theory (TDDFT) is a universal approach to the dynamical electronic many-body problem in atoms, molecules and solids. With TDDFT one can describe electronic excitation processes and calculate optical spectra of materials with unprecedented accuracy and computational efficiency. I will explain the formal background of TDDFT, give an overview of its broad range of applications, and discuss some of our own recent work on excitons and plasmons in solids and charge-transfer excitations in organic donor-acceptor molecules.
