Key takeaways

  • WCWN 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 WCWN to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of WCWN from memory before moving on to harder problems.

Reference excerpt

WCWN (channel 45, cable channel 15) is a television station licensed to Schenectady, New York, United States, serving the Capital District as an affiliate of The CW. It is owned by Sinclair Broadcast Group alongside CBS affiliate WRGB (channel 6). The two stations share studios on Balltown Road in Niskayuna, New York; WCWN's transmitter is located on the Helderberg Escarpment west of New Salem. WCWN brands as CW 15 after the cable channel position on Charter Spectrum and Verizon Fios.

History WCWN originated as an independent station on December 3, 1984, under the call letters WUSV, after its owner, Union Street Video. Chattanooga, Tennessee–based Media Central, a company that helped sign on a handful of independent UHF stations during this time, helped Union Street Video build the station, and also provided services to WUSV. However, it made little headway against the market's original independent, WXXA-TV (channel 23). As with most independent stations in mid-sized markets during that period, it had difficulties from the outset in terms of getting programming with only afternoon cartoons and some reruns getting respectable ratings. Most of the stronger programming went to WXXA, perhaps due in part to one of its founding partners, longtime movie director Arthur Penn, having ties to Hollywood. Also hurting WUSV was the presence of New York City's three independent stations–WNEW-TV (now WNYW), WOR-TV (now WWOR-TV) and WPIX–and Boston's WSBK-TV on cable, which had been the case for more than a decade. When WXXA joined Fox as a charter affiliate in 1986 (displacing WNYW on cable systems), WUSV had some difficulty filling the void. The Capital District was just barely large enough at the time to support what were essentially two independent stations (WXXA, like other early Fox affiliates, was still programmed as an independent at the time), and there simply wasn't enough programming to go around. Due to continuing financial difficulties, Union Street Video finally gave up in 1987 and sold the station in a fire sale to WMHT Educational Telecommunications on July 24, 1987. Under WMHT's ownership, channel 45 became a secondary PBS member station under the calls WMHX. It was still licensed as a commercial station, but operated as a non-commercial broadcaster—much like Buffalo's WNED-TV (which received an educational license in 2000) and New York City's WNYC-TV (now Ion Television owned-and-operated station WPXN-TV) operated for many years. This arrangement lasted until 1991 when, due to financial difficulties, WMHX was taken off-the-air. Two years later, the station returned to the air as WMHQ, carrying a large amount of instructional programming alongside repeats and double runs from WMHT. Further financial difficulties at WMHT led to WMHQ being put up for sale in the late 1990s. Despite WMHT's financial difficulties, WMHQ's commercial license was still very valuable. By this time, the Capital District had grown large enough that a second non-Big Three station was now viable. After a sale to Sinclair Broadcast Group, which intended to make the station a dual UPN/WB affiliate, fell through, Tribune Broadcasting, part-owner of The WB, bought the station in 1999 for $18.5 million. Channel 45's final day of programming as a PBS station was September 5, 1999; after its nightly midnight sign-off, it returned to the air at 6 a.m. the next morning as WB affiliate WEWB-TV, branded on-air as "WB 45". Prior to WEWB's relaunch, WPIX and WGN-TV's national feed had both served as the default WB affiliates for the Capital District. WPIX remained available to cable viewers in Albany until 2002, but was blacked out during WB programming as well as syndicated programming shown exclusively on Albany stations (due to syndication exclusivity rules). From the station's relaunch as WEWB until December 2006, its master control was located at sister station WB affiliate WLVI-TV in Boston. However, local offices were at Corporate Woods in Albany. WLVI's meteorologists maintained WCWN's weather page. In 2004, WEWB's digital signal signed on-the-air and began broadcasting on UHF channel 43. In 2005, the "WB 45" name was dropped in favor of "Capital Region's WB" at the tail end of a period in which most of Tribune's WB affiliates (minus its VHF and "heritage" stations) were re-branded in the same format. Eleven years after the births of UPN and The WB on January 24, 2006, it was announced by CBS and Time Warner that The WB would merge with its rival network, UPN, to form The CW. As part of the deal, the newly formed network signed a 10-year affiliation deal with 16 of Tribune's WB stations, including WEWB. In preparation, the station's call letters changed to the current WCWN on May 8. In July 2006, commercials for The CW as well as syndicated fall programming had the station rebranding as "The Capital Region's CW" effective with the network's launch on September 18. On June 19, 2006, Tribune announced it would sell WCWN to Freedom Communications, owner of CBS affiliate WRGB, for $17 million. The purchase faced review from the Federal Communications Commission (FCC) for much of 2006, since the Capital District has only eight full-power stations—not enough to legally permit a duopoly. However, the FCC granted Freedom a "failed station" waiver for the station's purchase on November 22, clearing the way for Freedom to close on the station on December 6. At that point, all of WCWN's operations were merged into WRGB's facilities in Niskayuna and Freedom began to maintain WCWN's website. The purchase gave the Capital District its first television duopoly. For a short period of time, this essentially gave WRGB control of three stations as it continued its pre-existing joint sales agreement (JSA) with MyNetworkTV affiliate WNYA until February 2007. Freedom announced on November 2, 2011, that it would bow out of television and sell its stations, including WCWN, to Sinclair Broadcast Group, marking the company's second attempt at acquiring channel 45. Since Freedom had acquired WCWN through a "failed station" waiver, Sinclair requested a similar waiver for the purchase; this was granted on March 13, 2012, as part of the FCC's approval of the transaction. The group deal closed on April 2, 2012.

Worked examples

Example 1 — a first encounter with WCWN

Start with the simplest possible case. Write down what WCWN 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 WCWN 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 WCWN 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 WCWN

In research
WCWN 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 WCWN 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
WCWN is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1984 establishments in New York (state), ATSC 3.0 television stations, Charge! (TV network) affiliates, so understanding it makes those chapters shorter.
In everyday life
Look for WCWN 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.
