I used to work for a Big Media Company. They used to scramble to by BigMediaCompany.<new tld> whenever there was a new tld.
Then one day they stopped. The legal department decided that if someone were to buy it and use it in a way that infringed on their trademark, it would be cheaper/easier to sue or file an injunction.
For a while it was an extortion game. A new .tld like ".mobi" or ".music" would start, and they'd offer the names to fortune 500 trademark holders for $$$$$.
