So I wouldn't claim yet that I have an answer as to how we can quickly change consumers' mindsets. I look back and say, TripAdvisor hasn't really had an awareness issue in most of our markets. TV does a great job growing awareness, so we see how it worked for so many other companies, but the companies have tended to be at a different awareness stage, at different growth stage and so we went forward with TV knowing that it wasn't to move our awareness numbers, but to educate folks on that one could now book on TripAdvisor. We did the surveys on the TV and certainly the book message stood out, but it was harder to see the behavior change on TripAdvisor. We saw more traffic. We made more money, but it was softer to draw the conclusion that it got people to actually complete a transaction to book on TripAdvisor. So it would be in my mind no harm whatsoever and configuring a TV campaign that has the same message or I'd like to be creative but the same we're different creative, something wrong with that couldn't possibly hurt, but in the judgment call of is that where we want to push on our branding and marketing for next year, we made the judgment call, because we have to make this one in advance, so if there is no, we're going to pause. I used the word pause carefully because I'm not saying we wouldn't change our mind, we wouldn't do something else in 2017 or maybe the late 2016, but the notion is that's not -- it's a big dollar, it's not what we're going to spend those dollars on in '16. When we look at it from -- wow, you have a 100 plus million travelers on the site in a month, 150 million, 175 million, surely that's a big enough sample size to work on the educational message, and recently we've been doing quite a bit on that. So if you go to the site, many of our devices not all, you will see a much stronger, you can book on TripAdvisor, and buying with the experience of [indiscernible] buzzer button, hundreds of thousands of property is plus the global rollout, plus the message of other brand communications that are different/cheaper than TV, you think that there is as I started with a judgment call, there something kind of wrong with the TV, but we think we can achieve our goals better in terms of training booked by spending our time and some of our dollars.
