The first historical direct observation of gravitational waves (GW150914) was accomplished by the Laser Interferometer Gravitational-wave Observatory (LIGO) on September 14, 2015. In this paper, we overview the observation of GW150914 and its data analysis including a validation of the detector's status around the arrival time of the event. We introduce two independent searches for transient gravitational waves and their results. We also present the contributions of the Korean Gravitational Wave Group (KGWG) to various aspects of the data analysis and the detector characterization within the LIGO Scientific Collaboration (LSC) and the Kamioka Gravitational-wave Observatory (KAGRA).
