Inside folder

Inside design for a folder gives it a little flare when taking out documents. Color inside also adds to the "flare". 

Petco

Petco's first logo was to complex with its overlapping reds; with the dog's ear on the "o" just being separated by the thick black outline. Spacing out the name from the illustration definitely helps the customer better understand the logo. Also adding in the light blue "healthy" to the new logo gives you a pure and clean feel when thinking about shopping their for your furry friends.

Wendy's

Simplified, focusing more on the girl than on a big sign with more than enough information on it. Everyone knows what Wendy's is so they no longer have to show its a "old fashion hamburger" restaurant.

Pepsi

Pepsi and its many years of perfecting a logo and brand type. Starting out red just like Coke. Adding in the blue in 1962, giving a different look from the normal colas using red logos. Now having the blue as a main focus with the hint of red in the illustration. 

Arby's

From simple to a metal looking sign. Personally I like the older logo better, it is not over done and easier to remember the simple pattern than the shines and curves of the new logo.

Ebay

Old overlaying text into a more simple and clean typeface. Making it easier to read when at different font sizes. Overlapping looses its form when really small and makes it harder for the viewer to acknowledge the companies name.

Starbucks

Another example of how Starbucks has simplified their logo throughout the years. Going from a complex brown image with text all around to an green image without the name since it is so recognizable.
