[Star Wars] How do organizations like the Trade Federation or Banking Clan have seats in the Galactic Senate?

My understanding was that only planets were represented in the Senate, yet both the Trade Federation and the Banking Clan have representatives. Are they representatives of a specific planet like Cato Nemodia represents all Trade Federation planets in the Senate? Or does each planet they control have a representative?

The economy of the Republic failed long before the current movies. About 50 years before PM the Republic issued two last ditch efforts to jumpstart the economy. One: isn't important. The second one gave Mega-corps seats in the senate. 

Thats why corporations have seats in the senate.
