The motivations for studying dynamical scenarios of electroweak and flavor
symmetry breaking are reviewed and the latest ideas, especially
topcolor-assisted technicolor, are summarized. Several technicolor signatures
at the Tevatron and Large Hadron Collider are described and it is emphasized
that all of them are well within the reach of these colliders. (This is the
written version of a plenary talk of this title at the 28th International
Conference on High Energy Physics, Warsaw (1996).)Comment: 11 pages including 3 figures; LaTeX using stwol.st
