Sometimes your logo or your product packaging needs a refresh. But retro is hip! So why not pull out the old packaging? Companies like Procter & Gamble, General Mills, Hostess Brands and PepsiCo are pouring new wine into old bags with brands like Tide, Cheerios and Doritos. Maybe you should not be to hasty with not renewing that one registration of your old logo. It may come in handy if retro is hip, again.
