YouTube succeeded where Google Video didn't because users were able to see their videos posted immediately, Google executive Marissa Mayer said at the Web 2.0 Summit here on Thursday.
"YouTube let people see the video right away," Mayer, vice president of search products and user experience, said during a short talk. "That's why it did so well."
By contrast, people posting to Google Video had to wait anywhere from two to four days for the video to be vetted and posted for public consumption, Mayer said.
Google announced that it was acquiring YouTube for $1.65 billion in stock last month.
In a survey on search, Google asked people how many results they would want by default; they responded that more is better, Mayer said. So the company conducted an experiment, providing some searchers with 30 default results. But it took, on average, a half-second longer to get those results than when the default was 10 results, she said. Out of frustration, people conducted fewer searches.
"This indicated extreme unhappiness," Mayer said. "It was clear that we weren't going to make this change."
Google applies this knowledge to the development of all its products, she said, adding that "the key motivator for us developing Gmail in AJAX was speed." AJAX, or Asynchronous JavaScript and XML, is a development method for writing interactive Web applications.
