The Washington Post has posted a nice little summary table titled "The Scanner Lobby". This table lists five companies, provides a one-sentence explanation about each company, the lists the dollars they spent on lobbying during 2009-2010 and how many millions they received in TSA contracts.

Here's the link: http://www.washingtonpost.com/wp-dyn...l?hpid=topnews

I am not a fan of the Post's incredibly crappy coverage of the TSA, but this summary chart is, IMHO, one thing they have done well.
