In practice, this term and a newer term, e-business, are often used interchangeably. For online retail selling, the term e-tailing is sometimes used.\n\nRequirements-Computer with internet connected,and any web browser

Don't count on it.\n\nThink about it...\n\nHow many sites have you found, that you liked, and often visit, as a result of a link exchange?\n\nProbably about zero.\n\nHow many sites have you ever visited?\n\nMaybe about 2,000.\n\nSo... do you like those odds?

There are more than 100 auction sites on the Internet but eBay has no serious competition. They are a whale swimming with minnows. eBay has more sales per hour than most auction sites have in a year. \n\nThis can be demonstrated. There are on-line services that search through all the on-line auction sites for an item you're looking for. Try any item and see where most are found. If the item is allowed on eBay, eBay will dominate the search results. \n\nAuctions A - Z\nAuction Watch\n\nEveryone who tries on-line auctions reports that if they want buyers, they have to be on eBay. If they're looking for tens of thousands of individual sellers eBay is the only place to find them. If they want to find a collectible, only eBay is where they can choose among, for example, 10 or more vintage Zenith Trans-Oceanic tube radios every week, week after week. \n\nThere's nowhere else on the planet to find that range of items. In all categories it allows, eBay has a lock on lookers, sellers, and bidders.

"Google is reported to search over 8 billion"... This information is about WEB PAGES, not DOMAINS. They have over 8 billions of web pages, in their index.\n\nActual count of domain names, in todays internet world is simply impossible to count. So, try to set your mind in something else, other than finding the total numbers of domain names!\n\n:-)

I find both wikipedia.com and epinions.com very helpful.  Both are open forums where anyone can post info about the ecommerce site. Wikipedia has a more objective tone, whereas as epinions has loads of content.
