Sports Phone

Sports Phone is a mathematics 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 Sports Phone rather than just read about it. In short: Sports Phone was a telephone service in the United States that allowed users to hear sports scores and information. The service was launched in 1972, and after initially failing it was relaunched three years later.

Key takeaways

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

Reference excerpt

Sports Phone was a telephone service in the United States that allowed users to hear sports scores and information. The service was launched in 1972, and after initially failing it was relaunched three years later. The service gained a following, and by 1981 had hit a peak of 50 million calls in a year. Sports Phone began in New York City, but expanded to offer programming in numerous other locations, including Chicago and Detroit. The rise of sports radio stations and score tickers on television broadcasts helped reduce the popularity of Sports Phone, before an increase in Internet usage led to its demise in 2000. Callers to Sports Phone heard messages of one minute or less, with up to 30 scores provided in a given update. In addition to scores, the service's programming included news and interviews, along with a sports trivia game. Some information was recorded specifically for certain markets. The announcers for Sports Phone included future broadcasters of several franchises in the major U.S. sports leagues.

History Sports Phone was first introduced on November 1, 1972, after a month of service testing. The original owner was New York Telephone employee Jack Goodfellow. Customers were charged 10 cents per one-minute phone call, with New York Telephone the recipient of all charges and a fee from Sports Phone for each call. Goodfellow's intention was for the service to make money from advertisements included with the service's updates, but the business model proved unsuccessful. In 1973, Air Time Inc., a media entity, purchased rights to the service. New York Telephone later allowed for information service operators to retain part of the call fees, and Sports Phone was relaunched in 1975. The service used multiple telephone numbers, including at least one alternate number, but the most well-known was 976-1313 (changed from 999-1313). Future broadcaster John Giannone claimed that, among New York City sports enthusiasts, "Everyone 45 and over can recite" the number. By 1976, Sports Phone was receiving an average of 65,000 calls daily. It appealed strongly to sports bettors, as it allowed users to access updates on games from the West Coast of the U.S., which frequently ended after broadcasts of television news programs. The service experienced a record period of activity in 1977, as the New York Mets were completing a trade with the Cincinnati Reds in which Tom Seaver was sent to the Reds. Sports Phone had 600,000 callers over a three-day span. The growth in Sports Phone's usage continued in the late 1970s and early 1980s. Daily call figures moved up to around 100,000 in 1979, with peaks of three times that figure on some weekend days when college or pro football games were being held. By 1981, New York Telephone was making $3 million from Sports Phone over a year; 50 million calls were made to Sports Phone that year; the only Dial-it service that received more activity was the one for off-track betting. The service expanded to markets outside New York City as well. In 1977, Sports Phone introduced a line with updates that focused on Chicago; two years later, Detroit received its own line. New Jersey and Buffalo were later added as markets with their own numbers. Daily call numbers in Chicago had hit around 65,000 by 1984, although they reportedly peaked at 175,000. Sports Phone had competition in the field by 1983, as a three-year-old national rival service, Dial-It, was receiving approximately 350,000 calls weekly. By 1985, Sports Phone's business model had changed, as its parent company, Phone Programs, was earning 2 cents per call from New York Telephone and making more than $1 million in revenue; this replaced a previous model in which Sports Phone received payments from AT&T before the breakup of the Bell System. Atlanta, Miami, and New Orleans had updates that were aimed at those markets by 1986. Calls to Sports Phone numbers cost 50 cents by 1986. The service was facing increasing competition nationally from providers such as JD's National Score Phone, Dial Sports, and a line from USA Today. Sports Phone indicated that it planned to increase call lengths to 90 seconds following the beginning of the football schedule; this matched the time of Dial Sports' calls, which cost customers 10 cents less. A radio station dedicated to sports programming, WFAN, debuted in New York City in 1987. The initial concept for the station included score updates every 15 minutes, which were inspired by Sports Phone. WFAN positioned itself to compete against Sports Phone for the attention of the service's callers. One of the station's first promotional advertisements contained the line "We just made Sports Phone old news." Sports Phone employee Cory Eisner said, "We knew right away (WFAN) was going to come after us." At the same time that sports radio was reducing the service's business, it was affected by an increase in the use of pagers by sports bettors and a rise in number blocks by businesses in the New York City region. Television stations also moved to provide scores to viewers, as both CBS and NBC added periodic score updates to their pro football telecasts. A Boston-area number was introduced in 1988, to coincide with the Mike Tyson vs. Michael Spinks heavyweight championship fight. Services were also provided to the Cleveland and Phoenix markets, but proved unsuccessful. By 1990, Sports Phone had received nearly one billion calls over the service's life. By this time, though, cable television sports stations were providing score updates. In future years, the Internet would offer scores and news in real time. Caller activity at Sports Phone fell to 1,000 or less daily. The service's last general manager, radio broadcaster Don La Greca, said of Sports Phone's decline, "Technology that helped us update then became available to the general public, and so there was no reason to have us." The service was shut down in 2000.

Worked examples

Example 1 — a first encounter with Sports Phone

Start with the simplest possible case. Write down what Sports Phone claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 Sports Phone 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 Sports Phone 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 Sports Phone

In research
Sports Phone appears in mathematics 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 Sports Phone 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
Sports Phone is common in secondary-school and first-year university syllabi. It links to neighbouring topics Information by telephone, Telephone numbers in the United States, so understanding it makes those chapters shorter.
In everyday life
Look for Sports Phone 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.
