As I manage my mom's domain, firstfood.com.sg, a scam email I received looked legitimate. Addressed to the CEO and Manager, it claimed to come from a domain registration and dispute organisation in Asia, handling companies' domain registration and IP protection.
The first .com domain ever registered was symbolics.com. Back then registering a domain cost far more than today's US$10 a year, so most names on the list belonged to multinational corporations. Surprisingly, Microsoft.com isn't among the earliest registrations.
I really don't think this is a good idea. Lawyers and analysts say ICANN's vote to allow any word as a top-level domain will cause URL chaos. Whenever ICANN needs money, they'll launch new TLDs companies must buy.
