You can can find Google's applications by looking under "Charleston Road Registry Inc.". Amazon is under their own name. Between the two of them, they have some pretty generic applications. i.e. ".lol", ".mom", ".pet" & ".soy"(?) etc...

It looks like Google only applied for 3 non-english TLDs. Amazon has closer to a dozen. Might say something about long term plans.

Microsoft has about a dozen applications, mostly for things they have trademarked. ".xbox" etc.

Apple is in there as well, but only for ".apple". ".app", ".tunes" were both applied for by Amazon.

I searched for .rugby. One is the IRB (the main governing body of rugby basically, which is understandable).

But also one from "dot Rugby Limited" which if you look closer, is a likely brand new LLC purely created to bid on domains. They also applied for .soccer, and the emails are all "icanntas<number>@famousfourmedia.com", the number I assume corresponding to the number of applications. Rugby is at 23.

Their site basically says "we're going to buy tlds to make money off".
