Internet
Yahoo
Yahoo was one of the internet's original giants — worth about $125 billion at the dot-com peak. It turned down Microsoft's ~$44.6 billion takeover in 2008, missed the shift to mobile and social, and after a failed turnaround under Marissa Mayer agreed in 2016 to sell its core business to Verizon for about $4.83 billion — a fraction of what it had walked away from.

Narrative
The story
The ambition
Yahoo was the front door to the early internet. Founded in 1994 as "Jerry's Guide to the World Wide Web," it grew into one of the web's original giants — a directory, then a portal, then email, news, finance, and sports used by hundreds of millions. At the height of the dot-com bubble in January 2000 its shares hit about $125 (split-adjusted), valuing the company at roughly $125 billion. It was, for a moment, the most valuable name on the internet.
The rise
It reached more than a billion users and owned some of the web's most-visited properties — Yahoo Mail alone had hundreds of millions of monthly users. Its ubiquity looked unassailable.
The cracks
But Yahoo missed the shifts that mattered. Its revenue peaked in 2008, the year after the iPhone launched, and then slid as users moved to mobile apps and younger, more focused platforms — Yahoo had the generation's biggest lead and never converted it, reportedly passing on early chances to invest in Google and Facebook. The clearest sign of trouble came in 2008: Microsoft offered about $44.6 billion to buy Yahoo outright, and Yahoo turned it down. Microsoft walked away, and Yahoo's value only fell from there.
The collapse
In July 2012 Yahoo hired Google executive Marissa Mayer to turn it around. She doubled down on mobile, redesigned core products, and bought companies — Tumblr for $1.1 billion, among many others — but the strategy was widely seen as confused, and none of it lifted the bottom line. By July 2016 the board had given up on independence: Yahoo agreed to sell its core operating business — advertising, content, search, and mobile — to Verizon for about $4.83 billion, roughly a tenth of the Microsoft offer it had rejected eight years earlier.
The aftermath
The sale laid bare where Yahoo's value had really gone: the deal excluded its stakes in Alibaba (worth more than $30 billion) and Yahoo Japan (around $8 billion), which together dwarfed the operating business Verizon was buying. In effect, an early bet on Alibaba was worth many times the company Yahoo had built. Mayer departed as the deal completed.
The lessons
A commanding lead is not a strategy, and the danger is not a single wrong turn but a decade of not adapting. Yahoo had the audience, the brand, and the balance sheet to own the mobile and social eras; it kept operating as a portal while the internet moved, turned down an offer that valued it at $44.6 billion, and ended up selling its core for a fraction of that. Incumbents rarely fail because a rival out-executes them once — they fail by assuming their position is permanent and declining to change while it still can.

- 2008
Missing the next era
Revenue peaked in 2008 as users moved to mobile and social; Yahoo held the biggest lead of its generation and never converted it. [2]
Failure to adapt - 2008
Turning down Microsoft
In 2008 Yahoo rejected Microsoft's ~$44.6 billion takeover; Microsoft walked away and Yahoo's value fell from there. [3]
Strategic drift - 2012
A turnaround that didn't turn
From July 2012 Marissa Mayer's mobile push and acquisitions (Tumblr, $1.1B) were seen as confused strategy and failed to lift the bottom line. [4]

Structured analysis
What Went Wrong
Root causes
Missed the mobile and social shift. Yahoo's revenue peaked in 2008 and then declined as users moved to mobile apps and younger platforms; it held the biggest lead of its generation and never converted it. [2]
A confused, unfixable turnaround. Marissa Mayer's mobile push and acquisition spree (including Tumblr for $1.1B) were widely seen as confused strategy and did not lift the bottom line. [4]
Contributing factors
Walked away from a $44.6B exit. In 2008 Yahoo rejected Microsoft's roughly $44.6 billion takeover offer; Microsoft walked away and Yahoo's value fell from there. [3]
Immediate trigger
Board sells the core business. By July 2016 the board gave up on independence and agreed to sell Yahoo's core operating business to Verizon for about $4.83 billion. [5]
Visible symptoms
Revenue peaked, then slid. Yahoo's revenue peaked in 2008 and declined as its audience migrated to mobile apps and rival platforms. [2]
Warning signs
Turning down $44.6 billion. Rejecting Microsoft's ~$44.6 billion offer in 2008 marked the high point of Yahoo's value; it fell steadily afterward. [3]
