In Response to Emma...

Can you think about the last product or service you really enjoyed and may have told your friends about? Do you think marketing by word of mouth has a big impact on sales?

I think that marketing by word of mouth is very influential. Personally I would value my friends opinion on a product or service more than anyone else because they know who I am.
The last product or service I thoroughly enjoyed was Bud Light Platinum. This new beer has more alcohol, 6% than the regular Bud Light and a different taste. The first time I heard about this beer was two weeks ago. My brother asked me to pick him up some Bud Light Platinum's on my way home from work. Since I had never heard of them, I decided to get myself some and greatly enjoyed them. When I returned back to school my roommates and I decided to grab some one night and they all enjoyed them as well.

I think marketing by word of mouth has some impact on sales. After you tell someone/are told by someone about a product, it is up to you as to whether you want to buy that product or service. Some people just brush off what you have just told them about a particular product or service, while others will value that opinion and buy into it.
