[1]: 11 On February 17, 1956, the Ministry of Posts and Telecommunications issued frequency allocations, and the Kantō region obtained three licenses in total.

[1]: 33  On January 9 of the following year, their broadcast license was approved, and test transmissions continued every night throughout the month.

So as not to run afoul of the educational TV license requirements, NET justified the airing of these programs under the pretext of "nurturing a child's emotional range" (子供の情操教育のため, Kodomo no jōsō kyōiku no tame) and "introduction of foreign cultures" (外国文化の紹介, Gaikoku bunka no shōkai).

[1]: 66  Two years later, NET announced its arrival into the anime race with the Toei produced Wolf Boy Ken.

Kenichiro Matsuoka, born in America and fluent in English, joined the board of NET and was responsible for licensing Laramie and Rawhide from the US, gaining high ratings for the network.

[7]: 61–62 In November 1964, Akao, together with shareholders other than Toei and Nikkei, Inc., succeeded in its major reorganization, forcing Ogawa to resign from the presidency.

[7]: 93 The following year, the Asahi Shimbun appointed to the post of station director Koshiji Miura (former Deputy Minister of Political Affairs).

[1]: 161–163 With the continuous network expansion, NET TV shifted its focus on its target audience again, this time from females, to being family oriented similar to the US PBS.

Toei's successful pitch was seen by its staff as a resurgence of their influence following the removal of Hiroshi Ogawa as president in 1964.

[1]: 209–214  Days later, the channel debuted another Ishinomori creation, Himitsu Sentai Gorenger, yet another Toei production, and it would be a stunning success (this was the same month when Kamen Rider jumped ship to rival TBS with the season premiere of Kamen Rider Stronger, the franchise would return to what is now TV Asahi in 2000).

The series marked the beginning of the Super Sentai franchise and established NET as a force to be reckoned with regarding tokusatsu productions and anime.

[1]: 264–265 In 1977, thanks to his close relationship with Ivan Ivanovich, head of the Japanese Section of the International Department of the Communist Party of the Soviet Union, Koshiji Miura was able to meet with Soviet leader Leonid Brezhnev and help TV Asahi obtain exclusive broadcasting rights for the 1980 Summer Olympics in Moscow.

[1]: 280–284 As a result, TV Asahi only aired high-profile Olympic events[1]: 284–287  and the broadcaster had significant losses in its revenue.

[1]: 316 TV Asahi collaborated with property development firm Mori Building Company to redevelop the Roppongi area.

While the new HQ was under development, TV Asahi temporarily moved to the newly built studios in Ark Hills.

[8]: 237–238 On November 22, 1995, TV Asahi premiered the American series The X-Files at an 8:00 pm prime time slot, the first since Knight Rider.

The station began airing the series due to the success of The X-Files in the Japanese home video market with 200,000 cassettes sold beyond the threshold of 10,000.

As part of the airing of the series, TV Asahi organized an "extensive promotional campaign" on the same month with a convention in Tokyo featuring screenings of episodes yet to release on home video and appearances by celebrity fans, Japanese translations of The X-Files books and an X-Files Mystery Tour to the filming locations of the series.

[7]: 238–244  In this regard, Toshitada Nakae personally went to the US to meet Murdoch and asked him not to increase his shareholding to TV Asahi.

[8]: 266–267  In 2004, TV Asahi's ratings reached 7.5% ranking third among the commercial broadcasters in the Kanto Region after a lapse of 32 years.

Disney-owned ABC signed a strategic alliance with former rival commercial broadcaster Fuji TV due to sluggish viewership ratings.

Partnership agreements with Zee Entertainment Enterprises Limited of India and the Kantana Group of Thailand were signed on March 31, 2015.

This was joined in November 1996 by a new special logo created following the launch of Iwate Asahi Television to represent the completion of the ANN network.

TV Asahi later updated its sign-on and sign-off video in 2008 with a revised version of computer-generated "sticks" animation and new background music.

The fonts used by TV Asahi for the written parts are Akzidenz Grotesk Bold (English) and Hiragino Kaku Gothic W8 (Japanese).

[16] From 1991 to 2001, TV Asahi was unique among the national television networks for its English language theme song, Join Us, which was used for both the startup and closedown sequences.

Before that, from 1977 to 1987, another song (わが家の友だち10チャンネル, Wagaya no Tomodachi 10 channeru, Terebi Asahi, also the name of the relaunch event on April 1, 1977)[17] was used for these (instrumental only from 1978, formerly with vocals).

Initially, it was planned that NET would become All Asahi Broadcasting Co., Ltd., and that it would also use AAB as an abbreviation, but the name had already been registered as a trademark and there were doubts about adding "All" to the name of a single company.
