Twitter's @tim_cook account went from six people to over 14,000 followers less than 30 minutes after its first no-nonesense tweet.

Apple CEO Tim Cook has learned a marketing trick or two from predecessor Steve Jobs. Cook posted his first tweet on Twitter Friday, the day Apple's new iPhones went on sale.

The tweet from @tim_cook was much like Cook himself: no-nonsense and direct, with a goal in mind: "Visited Retail Stores in Palo Alto today. Seeing so many happy customers reminds us of why we do what we do."

Twitter verified the account to NBC News on Friday.

Cook's account soared from six followers to more than 14,000 in under 30 minutes.

Among the Twitter accounts Cook has chosen to "follow" so far: coverage of Duke University basketball (Duke is where Cook got his master's degree), and Auburn University (where he got his bachelor's), as well as Laurene Jobs, Steve Jobs' widow. 

The CEO is also following Kerry Kennedy, president of the Robert F. Kennedy Center for Justice & Human Rights, and the center itself. Apple underlings Phil Schiller and Eddy Cue, and journalists Anderson Cooper of CNN and Thomas L. Friedman of the New York Times are on his "follow" list, as is comedian Jimmy Fallon, and, in a nod to music, Nashville-based Kings of Leon.
