The first radio telescopes used for astronomy operated at meter wavelengths or longer, but with the advent of better computers and new science cases, observations shifted to the centimeter regime. Centimeter observations are simpler than meter wave for several reasons, but over the last decade, several new meter wave radio telescopes have been constructed with the hope of observing a unique signature from the first stars and galaxies in the universe. I will present the science behind these observations and describe the latest efforts to detect long-wavelength cosmological emission from the early universe.
