Google: The problem with Glass is we kept telling people about it. Like, all the time.

But Teller believes that in marketing that program, Google made a mistake. He called the program itself a “great decision,” but argued that it wasn't positioned well. “The thing that we did not do well, that was closer to a failure, was that we allowed and sometimes even encouraged too much attention for the program,” Teller said. He added, “We did things which encouraged people to think of this as a finished product.” Instead, Google mostly wanted to learn what the social norms and uses would be, and didn't intend to make people think it was actually launching as a consumer product anytime soon — but that assumption was clearly widespread.
