Horizontal Market & Vertical Market

• 
  Vertical marketing is a term used to define a company's approach towards targeting that focuses on specific industries. For example, a software vendor might say "We concentrate on the following vertical markets: wood component manufacturers and thermoformed plastic manufacturers"
  

• 
  Horizontal marketing is when you single out a target audience that shares other characteristics, yet can be found in all industries. Common ways to horizontally market are by company size, by geography or by job title.
