The Asahi Broadcasting Group Holdings Corporation (朝日放送グループホールディングス株式会社, Asahi Hōsō Gurūpu Hōrudingusu kabushiki gaisha, ABC) is a certified broadcasting holding company headquartered in Osaka, Japan. Until March 31, 2018, it was a unified radio and television broadcaster serving in the Kansai region.

(大阪テレビ放送株式会社, Ōsaka Terebi Hōsō Kabushiki-gaisha, OTV) in Dojima, Kita-ku, Osaka. Currently, ANA Crowne Plaza Hotel Osaka is located at the place the head office of OTV used to be.
December 1, 1956 - OTV started television broadcasting on channel 6, under the callsign JOBX-TV (not to be confused with Oita Asahi Broadcasting which currently uses the JOBX callsign). The station was a primary KRT (TBS) affiliate with a secondary NTV affiliation.

January 1, 2008 - The ABC logo was redesigned, featuring the call letters ABC and the name "Asahi Broadcasting Corporation", "朝日放送", "Radio", or "TV" under the slope line from the letter "C".
