Early stages 
In early 1957, Youzo Kurosawa (then president of the Hokkai Shimbun), Yoshjiro Kikuchi (then president of the Hokkaido Charcoal Steamship Company), and Yoshitaro Hagiwara (president of the Hokkaido Charcoal Steamship Company), considered the formation of a second private television station in Hokkaido. Japan's national newspapers (Yomiuri Shimbun, Asahi Shimbun, Mainichi Shimbun, and Sankei Shimbun) attempted to enter the Hokkaido market at the time by combining two major sectors, television and newspapers, with the goal of creating a private television station. This is unquestionably a serious danger to Hokkaido's native newspaper, the Hokkai Shimbun. Hokkai Shimbun and an unnamed Hokkaido firm sought for a commercial TV broadcasting license under the name "Sapporo TV" in April 1957. And received their license on October of the same year. Founding and early years 

The company was founded on April 8, 1958.STV began its TV broadcasts on April 1 the following year airing for at least 9 and a half hours a day. STV started as a dual affiliated station with NNN as their primary affiliate and FNN as their secondary affiliate. The network also aired certain programming from Nippon Educational Television (currently TV Asahi) alongside HBC. Since Sapporo TV initially obtained a quasi-educational station license, the station had to follow educational quotas for a substantnial proportion of its programming. Sapporo TV's first self-produced program is also an educational program "Television Fudoki". In the first year of broadcasting, Sapporo TV's corporate income entered the top ten in Hokkaido. In 1960, the Sapporo TV Broadcasting Hall was completed, enabling Sapporo TV to have its own TV studio. In the same year, the Sapporo Television Union also announced its establishment. In 1961, STV's turnover reached 1.27 billion yen, and the average monthly turnover exceeded 100 million yen. Prior to its official TV broadcasts, STV also applied a radio broadcasting license in 1958 (which was later rejected). The broadcaster applied for a license again on February 17, 1961 and was granted on July 10, 1962 becoming the only broadcaster in Japan to start TV broadcasts then radio broadcasts (STV Radio started broadcasting on December 15, 1962). NET TV stopped providing programs to STV after it moved its remaining programs to HBC sometime in 1962. Relying on the principle of thorough budget frugality, Sapporo TV set a very high profit rate of 42.5% in the second half of 1963. In 1964, the station's signal had covered 95% of the population of Hokkaido. On March 20, 1966, STV started to air programs in color. STV joined NNN as one of its founding members on April 1, 1966, to strengthen the news reporting system. When the TV broadcasting license was renewed in 1967, the broadcasting license of Sapporo TV Station was changed from a quasi-educational station to a general TV station, withdrawing the former quotas introduced upon launch. The programming was more free and more entertainment programs were braodcast. Sapporo TV's program production ability also improved in the late 1960s, and in 1969, it assisted in the production of the popular late-night program 11PM  of the Nippon Television Network. In 1971, Sapporo TV Station built a new broadcasting hall, whose building area was three times that of the old broadcasting hall, and set up a special studio for TV news. In 1972, Sapporo TV also assisted in broadcasting the Sapporo Winter Olympics. STV ended airing programs from Fuji TV/FNN after UHB started broadcasting on April 1, 1972. Sapporo TV started was the first broadcaster to use the automatic advertising broadcast system. In 1978, the 20th anniversary of the broadcast, Sapporo TV produced special programs such as the documentary "One Year", and held special events such as "European Famous Paintings Appreciation Conference". In 1980, the turnover of Sapporo TV's television department reached 8.34 billion yen, and the revenue of the broadcasting department reached 1.736 billion yen. In 1984, the turnover of Sapporo TV's TV department exceeded 10 billion yen, and the broadcasting department exceeded 2 billion yen. In 1985, the listening rate of STV radio surpassed that of Hokkaido Broadcasting for the first time, and won the first place in Hokkaido. In 1991, Sapporo TV's TV department had a turnover of 13.374 billion yen, and its broadcasting department had a turnover of 3.21 billion yen, becoming the private broadcasting company with the highest turnover in Hokkaido for the first time. In 1993, to commemorate the 35th anniversary of the broadcast, Sapporo TV held the "Higashiyama Kaii" exhibition, which attracted 100,000 people to visit. In the same year, Sapporo TV's average audience rating for the whole day was 10.4%, the average audience rating for prime time was 16%, and the average audience rating for evening time was 15.3%. The first time to win the ratings triple crown in the Hokkaido area. In January 1996, Sapporo TV opened its official website. In 1998, the 40th anniversary of broadcasting, Sapporo TV opened a Berlin branch to strengthen the collection of overseas news. But in 2005, Sapporo TV closed the Berlin branch and opened the Moscow branch. In 1993, STV ranked number 1 in TV ratings for the first time.
