Excite.com
Yahoo was the most visited search engine on the planet in the 1990s and early 2000s, but excite.com was the second most visited search engine on the planet. So, in 1999, excite.com was offered to buy Google for $1 million, but excite.com’s CEO said no, which may have been the worst mistake they could have ever made.
Not only is Google worth an estimated $280 billion, but it’s also the most visited site in the world. Meanwhile, the mere mention of excite.com will have people shrugging their shoulder and scratching their heads because they’ve never heard of them.
