 It is the first in the Good things come to those who wait advertising campaign created by Abbott Mead Vickers BBDO who had won the Guinness account from Ogilvy & Mather in January 1998.
 The centrepiece of the "Swimblack" campaign is a 60-second television and cinema commercial written by Tom Carty, art directed by Walter Campbell and directed by Jonathan Glazer, which depicted an aging local sports hero's annual swimming race from an offshore buoy to his brother's seafront pub against the "clock" of pint of Guinness being "correctly" poured at the bar.
 The ad was shot in the remote Italian village of Monopoli and used local villagers for the crowd scenes.
 The aims of the campaign were to promote Guinness in general, to turn around the negative consumer opinion of the length of time required to correctly pour a pint of Guinness from the tap, usually quoted as 119.5 seconds, and to encourage bartenders to take the time to do so.

, while a man in a more formal suit-and-tie combination introduces himself as a Windows personal computer ("And I'm a PC.")

Make a Smellmitment is an advertising campaign created by Wieden+Kennedy for Old Spice in the United States.
 The campaign is preceded by “The Man Your Man Could Smell Like" which was a television advertising campaign by Wieden+Kennedy for Old Spice.
 The "Make a Smellmitment" campaign retains much of the format from the previous campaign including its characters played by Isaiah Mustafa and Terry Crews.
 The content of the new campaign ads also consist of character monologues during long single shots while engaging in random activities and addressing the female audience.
 The inaugural commercial, titled “And So It Begins”, lasts 1:02 minutes and introduces returning Old Spice actors Isaiah Mustafa as well as Terry Crews.
 This advertising campaign markets Wild Collection Bearglove Men’s Body Wash and Timber Bar Soap.
 Isaiah Mustafa and Terry Crews returned in their recurring roles from previous Old Spice advertisements.
 Mustafa’s character (referred to as the “Old Spice Man”) continues to target women despite marketing hygiene products for men as it was determined that women often buy household products for men.
 Terry Crews also reprised his Old Spice character that targets the male audience as he is always screaming and breaking things.
 The theme of the campaign focuses on the contrast between the smooth-talking monologues by Isaiah Mustafa and screaming Terry Crews interrupting each other as they advertise Old Spice Timber and Bearglove respectively.
 The commercials usually end with the two men each holding up their respective products side by side and pointing at them with Crews repeatedly yelling “Bearglove!”
 and Mustafa eventually saying “stop it”.
 "The point of it is more than just bringing two guys together.
 It's about helping people who think about or use Old Spice pick the scent that best fits their personality by connecting scents with the personalities of Isaiah and Terry", said John Sebastian, marketing director for Old Spice.
The Betty Crocker Kitchens are part of the test kitchens at the world headquarters of General Mills in Golden Valley, Minnesota.
 The Betty Crocker Kitchens were remodeled in 2003 and the facility contains 19 individual kitchens.
 They are modeled after and equipped like a kitchen you would find in someone’s home since the products and recipes tested are intended for home use.
 Majory Child Husted, an economist hired by the Washburn-Crosby company, was not only a key player in developing the persona of Betty Crocker but also recognized the subtle difference in how home cooks measured and approached recipes compared to how these recipes were made in the test kitchens.
 Based on her cooking instruction experience, Hustad felt that Betty Crocker’s recipes need to be reliable and fool-proof for the home cook.
 She passed her observations on to the company’s research department.
Betty Crocker is a fictional character used in advertising campaigns for food and recipes.
