Trying to make a successful blog

I use Blogger as my main site building tool....I searched some names on bloggrer I wanted to use and when I go to the site there is nothing on it at all and it was made in 2001......How can I get this blogger domain....Who do I contact?

There are good names on blogger that people snatched up and never did anything with it.....Google being as big as they are,they should put inactive names back on the market.
