Can someone help me with Indentify a product that could be promoted or advertise using a social networking sitewhy you think that product...

I social networking site provides same kind of benefits of
advertising to almost every product. The difference in utility of advertising for any
specific product is likely to be more closely related to the effectiveness of the
advertising for the product category itself rather than the match between product
category and the media (like social networking site). For example, advertising is more
effective for consumer products than for industrial products. This relative
attractiveness of advertising for consumer and industrial products will remain same for
any media such as TV or the Internet.

However effectiveness
of advertising of a product on a networking site is definitely likely to be more
effective if the product can be purchased on-line, for which a link is provided in the
advertisement it self. Here the criteria is not the type of product but place from where
it can be purchased. We can think of advertisement of  product on social networking site
with a link for on-line purchase, as on-line version of POP (point-of-purchase)
display.

Thus only guideline I will suggest for a product
to be advertised on the social networking site is that it should be a product sold
on-line, and the advertisement should contain a link to the website selling the product.
Of course, the person or the company advertising the product will restrict the choice to
a product marketed by the person or the company.
