about ebay

e Bay is the world's largest personal online trading community. eBay
created a new market: efficient one-to-one trading in an auction
format on the Web.

Individuals—not big businesses—use eBay to buy and sell items across
thousands of diverse categories, including collectables, antiques,
sports memorabilia, computers, toys, beanie babies, dolls, figures,
coins, stamps, books, magazines, music, pottery, glass, photography,
electronics, jewellery, gemstones, and much more. Users can find the
unique and the interesting on eBay—everything from chintz china to
chairs, teddy bears to trains, and furniture to figurines.

I took a strategic management course in college where I and others
completed a group project which included both an internal and external
analysis of eBay and the online auction website industry.  I am not a
researcher, but if this information might be valuable, you might be
interested in it as an additional resource.  I do not wish to take
work away from the GA researchers!  Let me know.
