(channel 6, callsign JOBX-TV) was a television station based in Osaka, operated by Asahi Broadcasting and New Japan Broadcasting (later Mainichi Broadcasting System). The company was founded in 1952 and began broadcasting on 1 December 1956. MBS left in preparation for the establishment of its own television station; this caused ABC to become the sole owner. The takeover began on 1 March 1959 and culminated on 1 June; after that it became ABC TV.

Background The idea of bringing commercial television to Japan stemmed from Yomiuri Shimbun president Matsutarō Shōriki, who in July 1952 would have a license granted for Nippon Television. At the time, several companies showed interest in a bid for an Osaka station, such as the Sankei Shimbun, Kyoto Broadcasting and the Yomiuri Shimbun. The two existing radio stations in Osaka, Asahi Broadcasting and New Japan Broadcasting, decided to reject their initial separate television license applications and joined their efforts under Osaka Television (name amended to Osaka Television Broadcasting the following year).

Preparations began in 1953 with the acquisition of a plot of land at Hamadori in the Dōjima neighborhood which would serve as its headquarters, and issued a logo design contest in newspapers. On 3 December 1955, the station obtained a preliminary license using the callsign JOBX-TV. It set up a 40% maximum for in-house productions and the rest would consist of programs from the Tokyo stations (KRT and NTV) to maximize profits. In order to boost its popularity, it installed sixty television sets in several parts of Kansai before its launch. By September 1956, the station hoped to be on air on 1 December and was already equipped with a US$190,000 remote unit. At the time, there were ane stimated 89,300 television sets for a population of nearly thirteen million people in Kansai.

On air OTV opened on target: test transmissions were conducted throughout November with two and a half hours of daily programming; then at 9:30a.m. on 1 December 1956, regular service began. Half of its programming at launch time consisted of dramas, viewer participation shows and news bulletins. OTV had strong appeal to television set owners; up until then, viewers had a habit of watching NHK (channel 4, later moved to channel 2).

In the summer of 1958, OTV acquired Japan's first videotape recording machines from US company Ampex, in a two-piece order. That year, it became the first television station to broadcast atop Mount Fuji.

KRT often used OTV as a talent pool, at a time where Osaka had four times the amount of talent available in Tokyo; 60% of OTV's programming was sourced from both KRT and NTV

Demise and collapse into ABC In January 1957, the Ministry of Posts and Telecommunications announced a new channel frequency plan, where Osaka gained more television stations. Both ABC and MBS wanted to establish their own television stations. Concerns over the limited amount of channels on the VHF band caused ABC to reject its plan, leaving MBS alone. ABC had no choice than to merge with OTV. 200 staff wanted to remain under the new company, while 104 opted to join MBS. With the launch of Yomiuri Television, Nippon TV decided to halt airing its programs on OTV; that station became its first commercial competitor.

With the opening of MBS on 1 March 1959, the station initiated a three-month transitional phase as ABC-OTV; on 1 June 1959, the merger was complete and the station became ABC TV, using the JONR-TV callsign.

Aftermath Following the OTV-ABC merger, ABC joined the Japan News Network and MBS joined a de facto network between it and Nippon Educational Television. This led to administrative problems that were only solved in 1975: up until then, ABC, affiliated to a Mainichi-backed network (JNN), was largely funded by the Asahi Shimbun, while MBS fared the opposite. The Asahi Shimbun held two meetings in 1963 and 1964 to find a way for NET TV to convert into a regular commercial station (which eventually became TV Asahi in 1977).

The JOBX-TV callsign now resides on Oita Asahi Broadcasting, which opened on 1 October 1993. JONR-TV (since 2003 operating as JONR-DTV; the analog calls were discarded in 2011) was later spun off at the beginning of fiscal 2018 (1 April 2018), whereupon it became JOAY-DTV.
