What is the difference between a crock pot and slow cooker? Both terms seem to be used for the same thing. Is this correct? Are they the same? Or is there some key difference between them?
Crock-Pot is a brand name. Slow cooker is the generic term.
It's like Kleenex & tissue or for the Brits, Hoover & vacuum.

"Crock-pot" has become a genericized brand name; any brand of slow cooker can be called a crock-pot, even though Crock-Pot is a specific brand. For more examples, see wikipedia's list of genericized brand names.
All crock-pots are slow cookers (in the USA), but all slow cookers are not crock-pots. For instance, I inherited a slow cooker from my mother that is essentially a non-stick casserole with a lid that sits on a separate warming unit not unlike an electric griddle. It's pretty useless for cooking, but a decent service unit.
EDIT: Obviously, it is marketed as a slow cooker. Equally obviously, it's not a crock-pot. Down-votes without explanation are very annoying. http://www.target.com/p/west-bend-oblong-slow-cooker-with-tote/-/A-10646883?ref=tgt_adv_XSG10001&AFID=Google_PLA_df&LNM=|10646883&CPNG=Appliances&kpid=10646883&LID=PA&ci_src=17588969&ci_sku=10646883&gclid=CIXhr9TbhroCFYk9QgodURQAUg
