KPLR-TV

KPLR-TV is a astronomy 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 KPLR-TV rather than just read about it. In short: KPLR-TV (channel 11), branded STL 11, is a television station in St. Louis, Missouri, United States, serving as the local outlet for The CW.

Key takeaways

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

Reference excerpt

KPLR-TV (channel 11), branded STL 11, is a television station in St. Louis, Missouri, United States, serving as the local outlet for The CW. It is owned by Nexstar Media Group alongside Fox affiliate KTVI (channel 2); Nexstar's Tegna subsidiary owns NBC affiliate KSDK (channel 5). KPLR-TV and KTVI share studios on Ball Drive in Maryland Heights; KPLR-TV's transmitter is located in Sappington, Missouri.

History

As an independent station

The station first signed on the air on April 28, 1959, as the first independent station in Missouri. The station's call letters were derived from the name of its founding owner, St. Louis real estate developer and hotelier Harold Koplar. Despite losing in his quest to build the station from the ground up, events effectively outside his control would allow him to acquire the license for the station in 1958. CBS was originally granted a construction permit by the Federal Communications Commission (FCC) to build channel 11 in January 1957, prevailing over three other locally based competitors. But eight months later, CBS decided instead to purchase its existing St. Louis affiliate, KWK-TV (channel 4). As a condition of the channel 4 purchase, the FCC required CBS to relinquish the channel 11 license and construction permit. CBS did so by transferring it to the Koplar group, known as "220 Television, Incorporated", for no financial consideration. Almost immediately, the three-way deal was held up after the St. Louis Amusement Company, one of the original applicants for channel 11, protested to the United States Court of Appeals in January 1958. The U.S. Supreme Court ultimately upheld the decision in November 1958, but CBS had already consummated its deal for channel 4 several months earlier, changing the station's call letters to KMOX-TV – which were intended for channel 11 – and operated it for 28 years (it is now Gray Television-owned KMOV). Meanwhile, Koplar went to work building channel 11 on his own, no longer in the face of opposition. KPLR originally operated from studios within the Koplar-owned Chase Park Plaza Hotel, located on Maryland Plaza in St. Louis' Central West End district. Channel 11 would move into a separate facility adjacent to the hotel several years later. Starting in the mid-1960s, Harold's son Edward J. "Ted" Koplar began working behind the scenes at KPLR, producing sports programming and developing the station's first regular local newscast. Ted Koplar became president and chief executive officer of channel 11 in 1979, and gained complete control of the station upon his father's death in 1985. For most of its existence, KPLR was a traditional independent station featuring cartoons, sitcoms, movies, drama series and locally produced newscasts. The station was also available on many cable systems in Missouri, Illinois and Arkansas as a regional superstation until the late 1980s. Locally, channel 11's first and only competitor came in June 1969, when Evans Broadcasting launched KDNL-TV (channel 30). The Fox affiliation for the market went to KDNL when that network launched on October 9, 1986. While this was part of a larger affiliation deal with KDNL's then-owner, Cox Broadcasting, most of the markets in KPLR's cable footprint had enough stations by this point to provide a local Fox affiliate. This would have made the prospect of KPLR as a multi-state Fox affiliate unattractive to the Koplars in any event. On January 17, 1994, the station began airing the Action Pack syndication block; the block's inaugural broadcast, the made-for-TV movie TekWar, earned locally an 11.2 rating/16 share, a 129% increase over that same time period during November 1993. In the summer of 1994, the station was approached by ABC to negotiate an affiliation agreement with the network to replace KTVI (channel 2) – which had been affiliated with ABC since it signed on as Belleville, Illinois–licensed WTVI on August 10, 1953 (when the station, then broadcasting on UHF channel 54, also maintained a primary CBS affiliation) – as its St. Louis affiliate. KTVI was among the thirteen "Big Three" network-affiliated television stations already owned or in the process of being acquired by New World Communications (and one of three out of the four stations that the group was acquiring from Argyle Television Holdings at the time) that were slated to switch to Fox under a long-term affiliation agreement announced between New World and then-Fox network parent News Corporation on May 23, 1994. Channel 11 station management would later turn the offer down; ABC instead reached an agreement with River City Broadcasting in August 1994 to shift the affiliation to outgoing Fox affiliate KDNL, which swapped network affiliations with KTVI on August 7, 1995.

Worked examples

Example 1 — a first encounter with KPLR-TV

Start with the simplest possible case. Write down what KPLR-TV claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 KPLR-TV 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 KPLR-TV 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 KPLR-TV

In research
KPLR-TV appears in astronomy 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 KPLR-TV 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
KPLR-TV is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1959 establishments in Missouri, ATSC 3.0 television stations, Comet (TV network) affiliates, so understanding it makes those chapters shorter.
In everyday life
Look for KPLR-TV 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.
