Yahoo’s Early Directory

In 1994, two graduate students at Stanford, Jerry Yang and David Filo, dreamed up a way to help early users navigate the web. They picked URLs that they each liked — beginning with around 100 links, including one for Nerf toys and one dedicated to armadillos — and listed them on a page called “Jerry and David’s Guide to the World Wide Web.” Within a year, their guide had to be divided into 19 categories (art, business, etc.) and was generating one million clicks a day.

.. In 2004, they grew again to $3.5 billion. At its peak, Yahoo’s market capitalization reached $128 billion. It was $20 billion larger than Berkshire Hathaway, Warren Buffett’s holding company.

.. Some 700 million people still visited Yahoo’s home page every month, making it almost seven times as large than the combined online audiences of The New York Times, The Daily Mail and The Washington Post.

.. But in Silicon Valley, the big money, and most of the prestige, is in making cool products. This is partly because product businesses, based on technology, are easier to scale than content ones, which require more human labor.
