 This is often done, so the viewers can make close correlation with an already existing non-fictional brand that they may use on a daily basis without having to create another fictional dimension for a separate product altogether.Some of the most popular TV series over the past decade have used this technique to allow their viewers to make that clear distinction, especially shows such as Scrubs where the protagonists are often seen mingling at a coffee shop known as "Coffee Bucks" which closely resembles the logo, colour and theme of a Starbucks.Similarly other TV shows such as My Name Is Earl also used similar technique with the fictional candy bar by the name of TitTat Candy, which closely resembles the Kit Kat chocolate bar, offered by The Hershey Company.
