Stock Trading and Other Things

What is the smallest market cap company in the stock market?

Im talking about the market capital of the company, both in US and Europe stock markets.
Also is there a limit to how small a company can be, to be listed on a exchange.

1. TLX, Trans-Lux Corporation with market cap of about $1 million.

Each exchange has their own (minimum) listing requirements.

Here are the NYSE's: http://www.cftech.com/BrainBank/FINANCE/NewYorkStockExch.html
