(Abstract only) Transiting exoplanets (TEPs), especially those found around bright stars, are particularly important as they provide unique opportunities to study the physical properties of planetary mass objects. The Hungarian-made Automated Telescope Network (HATNet) project—one of the small telescope surveys—has been extremely successful in the field of TEPs, contributing twenty-seven published discoveries, and one independent discovery of a previously published planet. Publications on several additional planetary systems are in preparation. I will discuss how HATNet operates around the globe, and how these fully automated small (11cm diameter) telescopes produce big science. I will also mention the related HATSouth project, now in full operation, and monitoring selected southern fields round-the-clock. Finally, I will conclude on how small and big telescopes collaborate in exoplanet science.
