This talk -- aimed at experimentalists and theorists -- describes low-scale technicolor (LSTC) and its phenomenology at hadron colliders. I begin with with a brief introduction/review of technicolor, extended technicolor and walking technicolor. These, especially walking technicolor, motivate the idea of LSTC. Its most important consequence at hadron colliders is the existence of very narrow spin-one technihadrons, produced as s-channel resonances, which decay to a technipion plus an electroweak gauge boson, pairs of EW bosons, and fermion-antifermion pairs. The CDF Collaboration has recently shown 3-sigma evidence for a narrow ~150 GeV particle produced in association with a W-boson and decaying to a pair of jets. This is the classic \rho_T -> W pi_T signature for LSTC. I'll discuss this signature, new cuts that can enhance its S/B, and other tests of LSTC at the Tevatron. I will also discuss searches that can and are being carried out at the LHC by ATLAS and CMS.
