Dex One Corporation was an American marketing company providing online, mobile and print search marketing via their DexKnows.com website, printyellow pagesdirectories and pay-per-click ad networks in the U.S.
In April 2013 Dex One merged with SuperMedia, and the combined company (after further acquisitions) now does business asThryv Inc.
Dex One Corporation was originally established as theR.H. Donnelley Company in 1886 by Reuben H. Donnelley, son ofRR Donnelley founder Richard R. Donnelley. R.H. Donnelley primarily contracted with The Chicago Telephone Company to publish telephone directories forChicago telephone customers. In 1906, the company began contracting withBell System firms such asNew York Telephone,Wisconsin Telephone, andCincinnati Suburban Telephone Co.
In 1917, The R.H. Donnelley Company was incorporated and moved toNew York City, retaining some offices inChicago. In 1929, Reuben Donnelley died; his company remained and continued to contract with theBell System to publish telephone directories nationally.
In 1961,R. H. Donnelley became a wholly owned subsidiary ofDun & Bradstreet.
Following its merger with Dun & Bradstreet, the company began a series of partnerships with additional telephone companies to publish directories. Around this time, competition started with other phone companies to provide directories.
From 1980 to 1985, R.H. Donnelley began a partnership with United Telephone (Sprint), called Uni-Don, to publish telephone directories to customers in centralFlorida.
In 1986, it contracted withNYNEX to become its directory sales agent. The same year, R.H. Donnelley started publishing directories inDelaware,New Jersey, andPennsylvania in competition withBell Atlantic, although a lot of these areas were later sold off toYellow Book.
In 1988, it formed Cen-Don with Centel (now part ofCenturyLink) to publish telephone directories inFlorida,Illinois,Iowa,Minnesota,Nevada,North Carolina,Ohio, andVirginia. Venture One was formed withSouthwestern Bell Corporation, which published directories in competition withBell Atlantic inBaltimore, MD andWashington, D.C.
In 1990, DonTech was formed withAmeritech to publish telephone directories in Illinois and northwestIndiana.
On July 1, 1998, Dun & Bradstreet split into two companies, one assuming the Dun & Bradstreet name, while the other adopting the R.H. Donnelley name.
In 2002, R.H. Donnelley acquired Sprint Directory Publishing, the publishing unit ofSprint Corp.
In 2003, R.H. Donnelley Publishing & Advertising, Inc., which published directories under theEMBARQ Yellow Pages name, was acquired from theSprint Corporation.
In 2004, R.H. Donnelley acquired the directory publishing business ofSBC Communications inIllinois and northwestIndiana, along with the SBC interest in DonTech. As a result, R.H. Donnelley gained a 50-year licensing agreement to use the SBC Yellow Pages name on all directories published for SBC Illinois customers. Following theAT&T merger, the directories were known as "AT&T Yellow Pages published by R.H. Donnelley".[2]
In 2006, R.H. Donnelley completed its acquisition ofDex Media, which had been spun off fromQwest in 2002-2003. Following the acquisition, R.H. Donnelley became the third largest directory publisher in theUnited States.[3]
In January 2007, R.H. Donnelley bought Local Launch Search Marketing[4] to add strength to its online marketing division for its yellow pages.
In July 2007, R.H. Donnelley boughtBusiness.com.[5]
On December 31, 2008, theNew York Stock Exchange (NYSE) suspended trading of R.H. Donnelley because the company's market capitalization was less than $25 million for 30 consecutive trading days, which failed to meet the Exchange's listing standards. As a result of this suspension, R.H. Donnelley began trading its common stock over-the-counter (OTC) on thePink Sheets beginning on January 2, 2009, under the symbol "RHDC".[6]
In June 2009, R.H. Donnelley Corporation and its subsidiaries filed for bankruptcy.[7] In February 2010, R.H. Donnelley Corporation emerged from bankruptcy asDex One Corporation.
On February 1, 2010, the New York Stock Exchange (NYSE) started trading 50 million Dex One Corporation shares under the "DEXO" ticker symbol.
On August 21, 2012, Dex One and SuperMedia announced a stock for stock merger transaction. The merger closed on April 30, 2013.[8] The new company is called Dex Media (not to be confused with the originalDex Media).[9]
The merger reunites directory operations formerly part ofAmeritech inIllinois,Verizon, andQwest, all of which haven't been under common ownership since theBell System divestiture in 1983.
