In 1949 Henry Taub founded Automatic Payrolls, Inc. as a manual payroll processing business with his brother Joe Taub. Frank Lautenberg joined the brothers in the company's infancy. In 1957, Lautenberg, after successfully serving in sales and marketing, became a full-fledged partner with the two brothers. In 1961, the company changed its name to Automatic Data Processing, Inc. (ADP), and began using punched card machines, check printing machines, and mainframe computers. ADP went public in 1961 with 300 clients, 125 employees, and revenues of approximately US$400,000.[5] The company established a subsidiary in the United Kingdom in 1965. In 1970, Lautenberg was noted as being the president of the company.[6] Also in 1970, the company's stock transitioned from trading on American Stock Exchange to trading on the New York Stock Exchange.[6] It acquired the pioneering online computer services company Time Sharing Limited (TSL) in 1974 and Cyphernetics in 1975. Lautenberg continued in his roles as Chairman and CEO until elected to the United States Senate from New Jersey in 1982.

From 1985 onward, ADP’s annual revenues exceeded the $1 billion mark, with paychecks processed for about 20% of the U.S. workforce. In the 1990s, ADP began acting as a professional employer organization (PEO). Around this time, the company acquired Autonom, a herman company,[citation needed] and the payroll and human resource services company, GSI, headquartered in Paris.[7] In September 1998, ADP acquired UK-based Chessington Computer Centre that supplied administration services to the UK Government.[8]

Kerridge Computer Co. Ltd., a dealer management systems (DMS) provider to auto dealers primarily in the UK was acquired in 2006.[9] In 2007, the ADP Brokerage Service Group was spun off to form Broadridge Financial Solutions, Inc.[10] On February 27, 2017, Automatic Data Processing Inc. confirmed it was closing its office in west Ann Arbor on March 30, 2017. At the time, ADP stated that it had around 56,000 employees worldwide, and that the year prior it had revenues of $12 billion,[11] or US$11,700,000,000 in 2016.[12] Also in early 2017, ADP described itself as the "largest provider of HR services in North America, Europe, Latin America and the Pacific Rim".[11]

In January 2018, ADP acquired WorkMarket, a New York City-based software platform company that helps businesses manage freelancers, contractors, and consultants.[13]

In August 1, 2018, ADP acquired Celergo, a company based out of Chicago IL. This company focuses in Human Capital Management in the global market.[14]

Divisions and spinoffsEdit

Broadridge Financial SolutionsEdit

In 2007, the ADP Brokerage Service Group was spun off to form Broadridge Financial Solutions, Inc. (NYSEBR), removing about US$2,000,000,000 from ADP's total yearly revenue.[10] ADP distributed one share of Broadridge common stock for every four shares of ADP common stock held by shareholders of record as of the close of business on March 23, 2007.[15]

CDK Global, LLCEdit

ADP Dealer Services in Ontario

Formerly called ADP Dealer Services, CDK Global was formed October 1, 2014 and provides integrated technology services and solutions to over 27,000 automotive dealerships internationally, as well as vehicle manufacturers.[16] In 2010, ADP acquired the automotive marketing company Cobalt.[17]

BZ Results (Automotive Dealer Services), winner of the 2006 “Innovative Company of the Year”,[18][19] was purchased by ADP in 2006.[20] At the time, BZ Results was valued at $125 million. On April 7, 2014, ADP laid off several Dealer Services associates in a reorganization and 3 days later announced plans to spin off the Dealer Services division as a standalone company.[21] On August 19, 2014, ADP Dealer Services announced that the name of the new company, post-spinoff, would be CDK Global (an acronym for Cobalt Dealer Kerridge).[22]

The Marcus Buckingham CompanyEdit

In January, 2017, ADP purchased The Marcus Buckingham Company[23] to strengthen its talent development offerings. Best known for the StandOut strength and character assessment tool for both leaders and associates, with the book StandOut 2.0: Assess Your Strengths, Find Your Edge, Win at Work published in 2015,[24] this addition offers ADP clients the people analytics they are wanting to provide better team collaboration based on individual character and personality assessments.
