In the spirit of Trimble's "Astrophysics in XXXX' series, I very briefly and subjectively review developments in SETI in 2020. My primary focus is 75 papers and books published or made public in 2020, which I sort into six broad categories: results from actual searches, new search methods and instrumentation, target and frequency seleciton, the development of technosignatures, theory of ETIs, and social aspects of SETI.
