The History of Telemarketing

By Victor Hoang · Updated Oct 24, 2026

The turning point was a pricing decision. Before 1961, the cost of each long-distance call was the main limit on how many buyers a company could phone. Then that limit moved. Call centers, scripts, registries and lawsuits followed.

Selling by telephone began almost as soon as shopkeepers learned customers would order that way. By April 1912, a business magazine was already reporting on stores trying to build phone-ordering habits. Telemarketing as an organized, high-volume practice took shape after AT&T launched flat-fee business calling in 1961. It drew its first federal rulebook with the Telephone Consumer Protection Act of 1991. The throughline: every time calling got cheaper, selling by phone grew, complaints grew with it, and lawmakers wrote a new limit that the next technology tried to get around.

Timeline at a Glance

The Counter Phone (1876-1950s)

Shopkeepers teach customers to pick up the phone

On March 10, 1876, in an attic laboratory at 5 Exeter Place in Boston, Alexander Graham Bell had called to his assistant, "Mr. Watson, come here! I want to see you." It took decades for anyone to treat that instrument as a way to sell.

The first sales use was inbound. In April 1912, Marshall Jewell Bailey wrote "Selling by Telephone" for System: The Magazine of Business, a survey of merchants trying to move orders onto the wire. A western department store printed a telephone catalogue with photographs of its operators so callers would feel they were reaching a real person. A tailor gave a five-cent rebate on phone orders. An eastern ice cream maker said 80 percent of his local business came by telephone. A Philadelphia department store credited about half of a 25 percent sales increase in 1911 to a telephone-order campaign. The article even says a salesman's territory could be extended as much as tenfold by using the phone. Those are the merchants' own reports, not audited figures, but they show the idea was already in circulation.

Keep the precursor apart from the concept. This was order-taking from known customers, closer to a clerk's work than to a quota-carrying seller. Selling at a distance by message is older than the telephone, and that longer story is told in the history of inside sales. What these shopkeepers established was a habit: customers would call a business.

What the era left unsolved was price. A call across a state was expensive, so a firm could answer the phone far more easily than it could dial out.

For teams today: the first phone channels worked because they made contact easy and told people the number. Check how hard it is to reach you before you worry about reaching others.

The WATS Years (1961-1970s)

Flat-fee calling turns the phone into a sales floor

The turning point is a billing change. AT&T launched Wide Area Telephone Service in 1961, designed to stimulate greater use of the telephone in sales and marketing, and it let subscribers place unlimited long-distance calls for a flat fee. In 1967 it added In-WATS, which reversed the flow and let callers dial a subscriber's line toll free. The history is told by Richard K. Popp in a 2014 Business History Conference paper, "Telephone Exchange: WATS, Direct-Response Selling, and the Marketization of the American Telephone, 1960-1973."

Popp describes two early ventures built on WATS. In 1967 the Chicago mail-order house Alden's took out a fifteen-page advertisement in the Saturday Evening Post to promote its "jet phone system," which let shoppers call in orders free of charge. In the same year the Campaign Communications Institute opened in New York City to sell campaign services to political candidates, and computerized calling programs were among its most popular products. It soon began marketing them to more traditional merchandisers. By 1973, Popp writes, WATS had become a trade worth more than $750 million to the Bell System.

His larger argument is that the phone network changed character. It moved from what he calls a "pseudo-public utility" to a resource that entrepreneurs could build a business on. The flat fee is the hinge. Once calls stopped costing money one at a time, the main expense of a phone seller became the salary of the person dialing. A manager's question moved from "can we afford to call?" to "how many calls can one person make?" For how field sales forces were organized before that shift, see the history of sales quotas and territories.

What the era created next was a volume problem. The more a company called, the more it needed lists, scripts and supervision, and the more it risked annoying the people it called.

For teams today: when the cost of a contact falls to near zero, the discipline shifts to quality. Cheap calling rewards the team that decides who not to call.

The Boom (1980s-1991)

Phone selling scales, and the complaints scale with it

By the early 1980s the business press had noticed. A January 11, 1983 Christian Science Monitor article by Francine Kiefer reported that the number of 800 numbers had risen 29 percent in 1982 over the year before, and that AT&T's own telemarketing center had pulled in more than $100 million in new revenue the previous year. Hubert Hennessey, a Babson College marketing professor, gave the reason: "It's the cost factor." A phone call could cost $4 to $5 or $20 to $40, depending on product and client, the article says.

The same piece corrects the idea that the practice was new. Gary Tobin, a spokesman for rival MCI, said: "The only thing new about telemarketing is the name." Large consumer companies were already running centers to answer customers. Procter & Gamble printed its 800 number on its products, and General Electric's center handled about 4,000 calls a day.

By the end of the decade Congress had measured the industry. The findings in the Telephone Consumer Protection Act, approved December 20, 1991, state that over 30,000 businesses actively telemarketed goods and services, that more than 300,000 solicitors called more than 18,000,000 Americans every day, and that US telemarketing sales were $435 billion in 1990, a more than fourfold increase since 1984. The same findings say unrestricted telemarketing can be an intrusive invasion of privacy, and that over half the states had already passed laws restricting phone marketing, which telemarketers could evade through interstate operations.

That last point explains why the federal law came when it did. A seller could dial across a state line, and a patchwork of state rules could not follow.

What the era created was a reputation problem. The tool that let a supplier serve a distant buyer cheaply also let a stranger with a script interrupt dinner, and the word "telemarketer" has carried that association since.

For teams today: a cost advantage is not a strategy. The firms that kept their phone channel respected used the savings to put better-prepared people on calls, not more people on scripts.

The Rulebook (1991-2003)

Congress, the FTC and the FCC draw the first lines

The TCPA was the first layer. Besides its findings, it defined "telephone solicitation" and excluded calls made with the person's prior permission, to someone with an established business relationship, or by a tax-exempt nonprofit. It restricted calls placed with an automatic dialing system or a prerecorded voice, including calls to emergency lines. It also reached the dialing machine, not just the pitch.

The second layer was fraud. Congress signed the Telemarketing and Consumer Fraud and Abuse Prevention Act on August 16, 1994, and the law directed the FTC to issue a rule within 365 days prohibiting deceptive and abusive telemarketing practices. The final Telemarketing Sales Rule was published in the Federal Register on August 23, 1995, and took effect December 31, 1995. In testimony to a House subcommittee in September 2008, the FTC's Lois Greisman said the agency had started more than 375 telemarketing cases since 1991, 110 of them before 1994.

Then technology forced a third layer. A predictive dialer, the FCC's 2003 order explains, is equipment that dials numbers and, with certain software, predicts when a sales agent will be available. It dials at a rate that ensures a person is free when a consumer answers. The side effect is the silent call, a ring answered by nobody. The FCC's July 2003 order, adopted June 26, set a limit: a telemarketer may abandon no more than three percent of calls answered by a person, measured over 30 days, and must play an identification message when it does. The FTC's rule, amended in December 2002, also prohibited call abandonment and required caller ID information to be transmitted where feasible.

Notice what this does to the work. A dialer raised the number of conversations per agent-hour, which is exactly what a call center manager wanted. The same machine raised the number of abandoned calls, which is exactly what a regulator didn't. A management tool became a compliance item. For how a modern prospecting call is built, see cold calling fundamentals.

For teams today: any system that raises your call volume needs a matching control on what it does to the person called. Measure the abandon rate the way you measure talk time.

The Registry Era (2003-2019)

A national list gives consumers a way to say no

The step that changed the business was the list. The FCC's order of July 2003 gives the argument: it concluded that a national do-not-call registry was warranted, and it notes that in 1992 some commenters had estimated the first-year cost of a list at as much as $80 million, while Congress had now approved $18.1 million for the FTC to build it. The same order records the view of many consumers that, with predictive dialers, the vices of telemarketing had become inherent and its virtues accidental.

The registry opened on June 27, 2003. The FTC reported that about 7 million numbers were logged on the Friday, 4.6 million on the Saturday and 2 million on the Sunday, for more than 10 million in the first weekend, with 85 percent of registrations made online. By the time the FTC testified in September 2008, consumers had registered more than 168 million numbers, and a Harris Interactive survey of October 2007 found that 72 percent of Americans had registered. In the FTC's account, more than 90 percent of those registrants reported fewer unwanted telemarketing calls.

The model spread. Canada's CRTC opened its National Do Not Call List on September 30, 2008, with exemptions for registered charities, newspapers seeking subscriptions, political parties and their candidates, firms with an existing business relationship in the previous 18 months, and organizations calling businesses. In the United States, FTC guidance likewise says most calls to a business made to solicit sales from that business are exempt from the Do Not Call provisions. The exemptions have conditions, so a team that sells to businesses should read the rule that governs its list.

The rules kept tightening around the dialer. The FTC amended its rule in August 2008 to bar telemarketing calls that deliver prerecorded messages unless the consumer has agreed in advance, with the change fully effective in September 2009. In February 2012 the FCC went further for the same kinds of calls: it required prior express written consent for all autodialed or prerecorded telemarketing calls to wireless numbers and residential lines, and eliminated the established business relationship exemption for those calls to residential lines. The same order added a way for consumers to opt out of future robocalls during a robocall.

Notice the pattern in the enforcement record. In its 2008 testimony the FTC described Operation Tele-PHONEY, a sweep it called the largest ever coordinated for the industry, with more than 180 civil and criminal actions. The agency also noted that calls placed from outside the United States create law-enforcement problems, because assets and evidence sit beyond the reach of US courts. The same testimony addressed a House bill that would have required call center employees to disclose where the center was located.

What the era created was a split. Consumers who had registered mostly got relief from legitimate callers, and the calls that kept coming were the ones that ignored the list.

For teams today: treat the opt-out as a permanent part of the channel. A list that respects the registry is smaller and better, and it protects the number you call from.

The Robocall Reckoning (2019-present)

Authentication, narrower definitions and AI voices

The problem had moved from legal telemarketers to illegal callers. Congress responded with the Pallone-Thune TRACED Act, approved December 30, 2019. It told the FCC to require voice providers to implement the STIR/SHAKEN call authentication framework on their internet protocol networks within 18 months, and it added a civil forfeiture penalty for violations of the robocall provisions. Authentication addresses the fact that a number on a screen can be faked.

Then the courts narrowed the target. In Facebook, Inc. v. Duguid, decided April 1, 2021, the Supreme Court held that to qualify as an automatic telephone dialing system under the TCPA, a device must have the capacity either to store or to produce a telephone number using a random or sequential number generator. The plaintiff, Noah Duguid, had received login-alert texts from a Facebook account he never created. The ruling matters to anyone whose system stores numbers and dials them from a list, because the statute's definition of an autodialer turned on how numbers are generated.

The newest technology came under the old statute. On February 8, 2024, the FCC ruled that calls made with AI-generated voices are "artificial" under the TCPA, which brings voice-cloned calls under the same consent requirement as prerecorded ones.

The numbers suggest the pressure is working, with a caveat: they count unverified complaints, not calls. The FTC's Data Book for fiscal year 2024 reported that robocall complaints fell from more than 3.4 million in fiscal 2021 to about 1.1 million, and that the registry held more than 253 million active numbers. Telemarketing did not disappear. It was fenced in, and the outreach that remained moved toward channels with their own rules, such as the email and video selling described in the history of inside sales.

For teams today: the legal question is increasingly about the system and the voice, not only the script. If you use automated dialing or synthetic voices, get consent in writing before the first call.

The Pattern Behind the History

Our synthesis, not published research. Call it Reach, Volume, Limit, Reroute:

• Cheaper reach opens the channel. A flat fee in 1961 turned calling from a cost per call into a cost per agent.
• Volume brings the complaint. By 1991 Congress had counted 18,000,000 calls a day and recorded the outrage.
• The limit follows the volume. The TCPA, the Telemarketing Sales Rule and the Do Not Call Registry each answered a specific excess.
• The technology reroutes. Predictive dialers, prerecorded messages and AI voices each found a gap, and each drew a narrower rule.
• What remains is permission. From the registry to the 2012 consent rule to the 2024 AI ruling, the legal line keeps moving toward whether the person asked.

What It Teaches Teams Today

• Treat consent as an asset. A permissioned list is the one part of the phone channel that regulators keep widening.
• Control the machine, not only the message. Dialer settings, abandon rates and caller ID are now compliance topics.
• Know which rules apply to your calls. The line between consumer and business calling is a legal design, so read the guidance for your case.
• Measure complaints with conversions. The history shows that volume alone eventually produces a limit.
• Use the phone where a person adds something. The channel survived by being useful to the buyer, and the best uses are the ones the buyer would choose.
