Marissa Mayer, VP of Search Products and User Experience at Google, sat on a panel at the AlwaysOn Summit over at Stanford University yesterday.  The theme of the panel was centered on the growing pains of innovation - how does a company grow while keeping its innovative edge? 

She cited a real life case based on her experience at Google.  Mayer explained that in the early days of Google, when it was still ad-free, users would email the company begging them to never put advertisements on the site - at the time, users were afraid of the annoying pop-ups we've all become too familiar with.  

But it was without a doubt that Google needed to make some money - otherwise the company which we benefit from today in our everyday lives - would probably gone belly up.

Eventually, Google figured out a way to show ads that complemented the search results. and become something Google users actually like.  According to Mayer these relevant ads produce, "greater user happiness."
