Reference excerpt

WXSP-CD (channel 15) is a low-power, Class A television station licensed to Grand Rapids, Michigan, United States, serving West Michigan. It is programmed primarily as an independent station, but maintains a secondary affiliation with MyNetworkTV. WXSP-CD is owned by Nexstar Media Group alongside NBC affiliate WOOD-TV (channel 8) and ABC affiliate WOTV (channel 41); Nexstar's Tegna subsidiary owns fellow ABC affiliate WZZM (channel 13). WXSP-CD, WOOD-TV and WOTV share studios on College Avenue Southeast in the Heritage Hill section of Grand Rapids; WXSP-CD's transmitter is located in Walker (along I-96). Another repeater station licensed to Grand Rapids, WOLP-CD (channel 35), utilizes and is co-located with WOOD-TV's transmitter southwest of Middleville.

History The station signed on the air on July 23, 1986, as W29AD, broadcasting on UHF channel 29. It moved to UHF channel 15 and acquired the W15AM calls on January 12, 1988. In the station's early days, it was a translator for World Harvest Television from WHME-TV in South Bend, Indiana, which is owned by LeSEA Broadcasting (now Family Broadcasting Corporation). The station was then purchased by LIN TV, the owner of WOOD-TV, and converted to the station's Local Weather Station (LWS) format with the call sign WOWD-LP (variation on WOOD-TV). WOWD and its low-power network of repeaters aired 24-hour weather information direct from WOOD-TV's weather center, including current conditions and severe weather coverage. This was in an early pre-digital format comparable to the now defunct NBC Weather Plus. The weather programming aired from the mid-1990s until it switched to a general entertainment programming format a few years later. It featured graphic displays of various current conditions and forecasts as well as periodic forecast segments from WOOD-TV's meteorologists. Short commercial breaks would feature promotional advertising for WOOD-TV's news and entertainment programming, as well as LWS' station identification. A format change took place when it became a UPN affiliate on August 31, 1999 (displacing that network from secondary carriage on WOOD-TV and WOTV), prompting the move of LWS to the early morning hours and the adoption of new calls, WXSP-LP. The call-sign WXSP-CA was acquired after it became a Class A station, which meets stricter requirements than most low-powered television stations. WXSP-CD continues to carry WOOD-TV's radar in late night weekend slots when paid programming is unable to be sold. On January 24, 2006, the Warner Bros. unit of Time Warner and CBS Corporation announced that the two companies would shut down The WB and UPN and combine the networks' respective programming to create a new "fifth" network called The CW. On February 22, 2006, News Corporation announced the launch of a new "sixth" network called MyNetworkTV, which would be operated by Fox Television Stations and its syndication division Twentieth Television. MyNetworkTV was created to compete against another upstart network that would launch at the same time that September, The CW (an amalgamated network that was originally consisted primarily of UPN and The WB's higher-rated programs) as well as to give UPN and WB stations that were not mentioned as becoming CW affiliates another option besides converting to independent stations. CBS affiliate WWMT (channel 3) announced on April 4 that it would affiliate with The CW on a new second digital subchannel. WXSP became available as a MyNetworkTV affiliate partly because then-WB affiliate WZPX-TV (channel 43) was also an i: Independent Television (now Ion) owned-and-operated station and ran WB programming on a 22-hour delay (prime time shows ran at 6 p.m. the night after the original broadcast and the Kids' WB Saturday block aired at 5 a.m. on Sunday mornings). As a result, Southwestern Michigan is one of the largest markets in which The CW was only available via digital subchannel/cable and on an entirely new station. It was reported that WXSP was in discussions to join The CW, but due to the station's heavy reliance upon professional sports during prime time and the network's concerns over preempted programming, the two sides could not come to an agreement. For the final two weeks of UPN's existence, Fox affiliate WXMI (channel 17) aired WWE Smackdown until WWMT-DT2's launch. WXSP joined MyNetworkTV on September 5, while WWMT-DT2 signed on with The CW on September 18. On July 21, 2010, WXSP flash-cut from analog to a digital signal. The call letters were changed to WXSP-CD on August 30. In late-October 2010, LIN TV discontinued the simulcast of WXSP on WOTV-DT2, replacing it with a new digital subchannel network, TheCoolTV (which it discontinued on July 15, 2013). On July 1, 2013, LIN TV ended the simulcast of WXSP on WOOD-DT2, replacing that signal with Bounce TV. On March 21, 2014, it was announced that Media General would acquire LIN. The deal closed on December 19, bringing WXSP, along with WOOD and WOTV, under common ownership with CBS affiliate WLNS-TV in Lansing. On January 27, 2016, Media General announced that it had entered into a definite agreement to be acquired by Nexstar Broadcasting Group. The combined company was named Nexstar Media Group, and owned at the time 171 stations (including WOOD, WOTV and WXSP), serving an estimated 39% of households. Due to their low-power status, the WXSP-CD network of stations was not affected by the Nexstar-Tribune merger involving the spin-off of Tribune's WXMI to Scripps. In August 2025, Nexstar Media Group agreed to acquire Tegna for $6.2 billion. In Grand Rapids, Tegna already owns WZZM.

Programming Overnights, WXSP airs a live feed of WOOD-TV's Doppler weather radar (known as "Storm Track Live"), along with NOAA Weather Radio broadcast audio. The station may sometimes air ABC or NBC programming in the event of preemptions by WOTV or WOOD-TV. The station was the Grand Rapids home for the former Detroit Pistons, Detroit Red Wings, and Big Ten Conference syndicated packages. In 2024, the station announced a broadcast agreement with the Grand Rapids Rise of the Pro Volleyball Federation.

Newscasts On October 21, 2007, WXSP introduced a 10 p.m. newscast produced by sister station WOOD-TV, titled News 8 at 10:00. The half-hour newscast competes with Fox station WXMI's hour-long prime time newscast, as well as a newscast on WWMT's second subchannel that debuted in 2008.

Worked examples

Example 1 — a first encounter with WXSP-CD

Start with the simplest possible case. Write down what WXSP-CD 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 WXSP-CD 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 WXSP-CD 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 WXSP-CD

In research: WXSP-CD 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 WXSP-CD 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: WXSP-CD is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1986 establishments in Michigan, ATSC 3.0 television stations, Ion Mystery affiliates, so understanding it makes those chapters shorter.
In everyday life: Look for WXSP-CD 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.
