Mark Pincus started building companies around the beginning of the Internet. He watched way Yahoo had made itself into a massive portal with millions of users–it became a pillar of the Internet. After founding and selling several companies, he decided that’s what he wanted to build.

“I wanted to create one of those forever branded services… A digital skycraper,” he said. ” We’re living in this short period time where… we all have the chance to create one of those forever brands that people can’t imagine life without and can’t remember before.”

In the way that many of the skyscrapers of today were built by the hundred-year-old-brands of the industrial age, he wants Zynga to be around for 100 years. “It would be arrogant and presumptive to think that could happen. I know that social gaming may not be called social gaming forever, but people playing games together will be around in 1000 years,” he said.

“What we’re doing is the precursor for what people will be doing in 100 years, it’s up to us to innovate and earn a place in their lives.” He added that Amazon is a company that’ll be around in 100 years, and that there is plenty of room for many “digital skycrapers.” Building a company that’s big for ten years seems like “a footnote in history.”

Pincus spent a lot of time on the CEO letter in his company’s S-1 filing before going public, because he wanted it to stand the test of time. Google’s CEO letter and Amazon’s CEO letter were sources of inspiration.
