Talk:List of companies based in the Philadelphia area

Inclusion criteria
I've been struggling with determining exactly how to evaluate companies to put on this list. My working criteria for inclusion are listed below:

Eligibility

 * Must be within the "Delaware Valley" Census designated place.
 * Including: Phila, Wilmington, Camden, Reading (new for most recent CDP def.)
 * Not including: Atlantic City, Trenton, Harrisburg, Lehigh valley
 * Law firms and other professional partnerships are eligible.
 * Local companies that were acquired by non-local companies are eligble. (PECO, SmithKline)
 * Companies of the past like PRR and Reading are eligible.
 * Government agencies like PGW and PWD are not eligible.
 * Non-profit agencies like IBX are not eligible, despite being incorporated.

Notability
Specifying notability requirements is harder. Special attention will be paid to headquarters within Philadelphia. I'm just throwing out numbers here:
 * Fortune 1000 members certainly included.
 * Companies with over $100M annual revenue included.
 * Companies with more than 250 employees included.
 * Phila based companies with over $25M annual revenue considered.
 * Phila based companies with more than 100 employees considered.
 * Well known consumer brands should be included. Public knowledge may be primarily in the DelVal area.
 * Companies with buildings named after them are notable and should be mentioned no matter what their current status is. -- Austin Murphy (talk) 18:24, 7 December 2007 (UTC)
 * Since this was written, Wikipedia has developed a standard for this kind of thing: "In general, a person or organization added to a list should have a pre-existing article before being added to most lists." Thus Aramark would qualify, Joe's Corner Store would not. It's very straight forward: Blue links are included, red links are not. "Philadelphia area" is a bit vague. I can't really see a justification for excluding public utilities and non-profits. Thoughts? - Sum mer PhD  (talk) 21:03, 8 May 2014 (UTC)
