What Organizations Pay to Lobby

Out of pure curiosity, I was wondering what some of the organizations I belong to paid lobbyist.  I came across a website that allowed me to search all kinds of organizations and what they paid to lobbyists.  If you believe that money buys influence, you can really see who is doing the buying.  According to the website,  2.21 billion dollars was spent last year in reported lobbying costs.   My lawyer groups spent 25 million lobbying, which is a lot of money,  but is .01% of the total amount.
