Yeah, good questions. Thanks, Tim. So in terms of new things, marketers have new problems, and so it's less about a sort of discretionary, let's double in some new toys. It's more about how do I get the – what do I need, what tools do I need, what platforms do I need to get the right message out to the right person at the right time and particularly, given this environment, how can I do that most effectively? And so app install is a perfect example of that, whereby that there is a channel for brand owners for advertisers to get to consumers and – on the phone right in front of people, who are spending more time on the phone than they ever have. And so it makes a ton of sense for them to move toward things that are going to help them with their business rather than just be something that they experiment. So that's the sort of trend we've seen in terms of app install. And I think the same applies to Retail Media as well as to – how do I utilize a network to be able to create a shopping environment, and that's just as a response to a need. And so we're proud that we can service those needs and we'll continue to talk to clients and look at the marketplace for new opportunities for us. On the Nielsen side, well, look, I love this one. Nielsen, our -- yeah, our currency provider -- third-party independent measurement provider, it's important for us to make sure that our clients have transparency, and so what it is that we provide them beyond performance, but also that they know that they got to the right person and that's what Nielsen does. It's just layer on an extra piece of third-party validation that there – the work that we've done as – that they've got what they paid for, put it that way. And both in terms of ad writing, ad writings is a powerful one because it's able to measure a advertiser's reach, if you like, across platforms. It's able to compare what we do for them in a digital environment to their campaigns as they run across TV, that's an incredibly powerful thing. And also -- and digital brand effect that shows what the uptick of the brands, the brand equity well or do I remember the brand, does it change my decisions there to purchase et cetera. So, these sorts of metrics that we don't necessarily provide, but we think a fundamental add-ons to performance to actually sell a product. So, I love this one clearly for obvious reasons and I do hope that and feel good about a deeper and wider relationship with Nielsen.
