In a highly publicized move, Yahoo! redesigned their logo with design efforts led by CEO Marissa Mayer. She says in an article in Ad Age:
"On a personal level, I love brands, logos, color, design, and, most of all, Adobe Illustrator. I think it's one of the most incredible software packages ever made. I'm not a pro, but I know enough to be dangerous :) So, one weekend this summer, I rolled up my sleeves and dove into the trenches with our logo design team"
Obviously, Yahoo didn't design their new logo in-house because of economic reasons.
Oops. I forgot to add in the price of pizza.
