KCCI

KCCI is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand KCCI rather than just read about it. In short: KCCI (channel 8) is a television station in Des Moines, Iowa, United States, affiliated with CBS. Owned by Hearst Television, the station maintains studios on Ninth Street in downtown Des Moines and a transmitter in Alleman.

Key takeaways

  • KCCI belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect KCCI to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of KCCI from memory before moving on to harder problems.

Reference excerpt

KCCI (channel 8) is a television station in Des Moines, Iowa, United States, affiliated with CBS. Owned by Hearst Television, the station maintains studios on Ninth Street in downtown Des Moines and a transmitter in Alleman.

History KCCI started on the air on July 31, 1955, as KRNT-TV, the third television station in Des Moines and the ninth in Iowa. It was owned by the Cowles family, publishers of the still-operating Des Moines Register and the defunct Des Moines Tribune newspapers, along with KRNT radio (AM 1350 and the original KRNT-FM at 104.5, which went dark). The calls stood for the papers' nickname in central Iowa, "the R 'n T". The Cowles family and rival KSO radio (now KXNO, also owned by the Cowles interests until 1942) both applied for the channel 8 construction permit. A decision was held up due to issues with the Cowles' ownership of Look magazine. Eventually, the two stations reached a settlement that allowed KRNT to own 60 percent of the TV station and KSO to own 40 percent. Once the Federal Communications Commission (FCC) approved the station's license, KRNT immediately bought out KSO's share of the station. KRNT-TV's broadcasting day was originally about five to six hours long, and included a 15-minute news program later in the evening. The station has been part of the CBS television network through its entire history, owing to KRNT radio's long affiliation with the CBS Radio Network. The FCC tightened its ownership rules in the 1970s, forcing the Cowles interests to sell one of their Des Moines broadcast outlets. They opted to sell KRNT radio and KRNQ-FM (KSTZ, originally the second KRNT-FM) to Stauffer Communications in 1974 and retain both newspapers and KRNT-TV, with the callsign changing to KCCI-TV on February 25; the new calls standing for owner Cowles Communications, Inc. (FCC rules at the time had a restriction on call letters being used by TV and radio stations in the same market, but with different ownership, which led to the TV station changing its callsign.) Over the years, Cowles Communications bought several other media outlets, including KTVH (now KWCH-DT) in Hutchinson, Kansas (and its satellites in the western part of Kansas), WESH-TV in Daytona Beach, Florida, and WQAD-TV in the Quad Cities area. In 1983, the Cowles family announced it was breaking up its vast media empire, selling off most of its assets except the Minneapolis Star Tribune. While the Register went to the Gannett Company and the Register and Tribune Syndicate (best known as syndicators of The Family Circus) went to the Hearst Corporation's King Features Syndicate division, KCCI and WESH went to H&C Communications. Cowles earned a handsome return on its purchase of KRNT radio's predecessor, the original KSO, in 1932; the call letters became KRNT in 1935. After initially planning on selling its entire television station group to Young Broadcasting in 1992, H&C sold KCCI and WESH to Pulitzer in 1993. Hearst-Argyle Television bought all of Pulitzer's television holdings in 1998. KCCI began broadcasting in high-definition television on channel 8.1 in 2002. On July 24, 2006, KCCI launched "Weather Now", a 24-hour local weather channel that appeared on digital subchannel 8.2 as well as local Mediacom digital cable channel 247, and the station's website until June 30, 2011. On July 1, 2011, KCCI replaced the weather channel with MeTV on subchannel 8.2. The station operates a website at www.kcci.com. For several years the station's website was known as www.theiowachannel.com, following the practice of other Hearst-Argyle stations, and people going to kcci.com were redirected to theiowachannel.com. In October 2005, the station switched back to the kcci.com name for its web site, with theiowachannel.com serving as a redirect to kcci.com. On December 10, 2008, KCCI president and general manager Paul Fredericksen announced a staffing reorganization which eliminated six positions, including on-air talent.

Weather beacon A 200-foot (61 m) weather beacon was once affixed to the auxiliary tower atop the station's downtown Des Moines studios and was a landmark of the Des Moines skyline. The lighted beacon changed colors depending on the forecast:

Weather Beacon red, warmer weather ahead. Weather Beacon white, colder weather in sight. Weather Beacon green, no change in forecast foreseen. Weather Beacon flashing night or day, precipitation is on the way. The beacon was active until the 1970s energy crisis, then powered back up by the station in 1987. An ice storm in January 2010 damaged the weather beacon, but it was repaired later that year. The weather beacon was permanently shut down on the morning of Thursday, September 27, 2012.

Worked examples

Example 1 — a first encounter with KCCI

Start with the simplest possible case. Write down what KCCI claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to KCCI before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about KCCI ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of KCCI

In research
KCCI appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses KCCI in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
KCCI is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1955 establishments in Iowa, CBS affiliates, Hearst Television, so understanding it makes those chapters shorter.
In everyday life
Look for KCCI outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is KCCI in simple terms?

KCCI (channel 8) is a television station in Des Moines, Iowa, United States, affiliated with CBS. Owned by Hearst Television, the station maintains studios on Ninth Street in downtown Des Moines and a transmitter in Alleman.

Why does KCCI matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study KCCI?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
