When Tech Ate Tech

The Despoiler's third ledger counts 331 deals in which one American tech, telecom or media company swallowed another, worth about $5.1 trillion in today's dollars, led by AOL's purchase of Time Warner.

The phone company bought the cable company. The cable company bought the studio. The internet company bought the magazine empire. Then most of them got bought again.

Ledger No. 3, The Despoiler's record of American tech companies buying each other, lists 331 completed deals from 1929 through Sept. 26, 2026. Both buyer and target had to be U.S. companies in technology, electronics, telecom, cable, media, audio/visual equipment or video games. Each headline price is adjusted to August 2026 dollars using the federal Consumer Price Index.

Together the deals total about $5.1 trillion in today's money.

The biggest deals

Nothing comes close to AOL's purchase of Time Warner, which closed in 2001 at $165 billion, or about $312 billion today, according to the ledger.

AT&T's 2018 purchase of Time Warner, at $108.7 billion including debt, ranks second. AT&T's 2006 purchase of BellSouth, at $86 billion including debt, is third.

The pattern: wires and airwaves

Eight of the top 10 are telecom and cable deals. The ledger counts telecom and cable for about 38% of the total value of all 331 deals, and media, audio/visual and games for about 25%.

AT&T alone appears as buyer in five of the top 10. Many of those deals reassembled pieces of the old Bell System. SBC bought Ameritech, Pacific Telesis and, in 2005, AT&T itself, taking the AT&T name, according to the ledger.

The 2000s lead all decades, at about $1.76 trillion in 2026 dollars, because AOL–Time Warner and the late-1990s telecom and cable consolidation closed between 2000 and 2006. The 1990s follow at about $950 billion.

Before 1969, the ledger finds no deal in these industries with a documented price above a few billion in today's money. It credits AT&T's regulated monopoly, the 1948 Paramount decree breaking up studio theater chains and antitrust enforcement for keeping big mergers off the table. The earliest priced entry is Xerox's 1969 purchase of Scientific Data Systems, paid in stock, for $950 million.

2026 so far

Six deals in the ledger closed in 2026. The largest is SpaceX's all-stock $60 billion purchase of Anysphere, maker of the Cursor coding tool, in August. Charter closed its $34.5 billion purchase of Cox Communications in August, and Google closed its $32 billion purchase of Wiz in March.

Verizon's $20 billion purchase of Frontier, IBM's $11.6 billion deal for Confluent and Amphenol's $10.5 billion purchase of CommScope's connectivity unit round out the year.

Not yet counted is Paramount Skydance's $111 billion purchase of Warner Bros. Discovery, which the ledger reported was expected to close by Oct. 1, 2026. Once closed, it would rank about eighth.

The Dayton angle

The ledger's lone Dayton entry is a painful one: AT&T's hostile 1991 takeover of NCR for $7.4 billion, about $18.2 billion today. Ledger No. 1 ranks it as the second-largest sale of a Dayton company. NCR moved its headquarters to Georgia in 2009.

Read with care

Of 331 deals, 62 are marked verified, 103 came from published acquisition lists without a second check, and 166 are compiled from general knowledge. The ledger says to "treat the lower part of the ranking as incomplete," and leaves out private equity buyers, foreign buyers or targets, and blocked deals.
