The largest merger in history at the time combined a dying dial-up ISP with a media giant, destroying $200 billion in shareholder value and becoming the textbook case of dot-com era hubris.

Microsoft bought Nokia's phone division to compete with iPhone and Android, wrote off the entire acquisition within a year, and laid off 18,000 employees — Steve Ballmer's most expensive mistake.

HP paid a massive premium for British software firm Autonomy, then accused its founders of accounting fraud and wrote off $8.8 billion, triggering lawsuits that dragged on for over a decade.

Marissa Mayer's Yahoo bought the blogging platform for $1.1 billion, killed its NSFW content that drove engagement, then sold it to Automattic for reportedly under $3 million — a 99.7% loss.

Google bought Motorola primarily for its patent portfolio, failed to make its smartphones competitive, then sold the hardware division to Lenovo for $2.91 billion just two years later.

Zuckerberg's $2 billion acquisition of Oculus ballooned into a $50 billion metaverse money pit as Reality Labs hemorrhaged cash quarterly while consumer VR adoption remained stubbornly niche.

IBM paid a record premium for open-source giant Red Hat hoping to revive its cloud business, but five years later IBM's cloud market share remains a distant fourth behind AWS, Azure, and Google.

Though not purely tech, this acquisition destroyed Snapple's quirky brand identity through corporate mismanagement, and Quaker sold it just 27 months later for $300 million — losing $1.4 billion.

eBay bought Skype believing voice calls would transform online auctions, realized the synergy was imaginary, wrote off $900 million, then sold a majority stake to private investors at a massive loss.

Musk bought Twitter for $44 billion, fired 80% of staff, rebranded it to X, drove away advertisers, and watched its estimated value plummet to roughly $12 billion within two years of ownership.
