In the following years, the other businesses in the Universal Food Systems portfolio were sold or closed, and the company was renamed to Dunkin' Donuts. The menu and shop format was standardized, and various new menu items were introduced. In the early 1980s counter service and ceramic coffee cups were replaced by self-service counters and paper cups.{{sfn|Rosenberg|2020|p=129}} The chain [[Initial public offering|went public]] in 1968<ref name="around">{{cite book|title=Around the Corner to Around the World|first=Robert |last=Rosenberg|publisher=Harper Collins|year=2020|isbn=978-1-4002-2048-9|page=40}}</ref> and was acquired by [[Baskin-Robbins]] owner [[Allied Domecq|Allied Lyons]] in 1990.<ref>{{cite news |title=COMPANY NEWS; Dunkin' Donuts Agrees to Sale |url=https://www.nytimes.com/1989/11/18/business/company-news-dunkin-donuts-agrees-to-sale.html |access-date=October 15, 2023 |work=The New York Times |date=November 18, 1989}}</ref><ref>{{Cite book|url=https://archive.org/details/mergersacquisiti00gaug|url-access=registration|title=Mergers, acquisitions, and corporate restructurings|last=Gaughan|first=Patrick A.|year=1996|publisher=John Wiley & Sons|isbn=978-0-471-13145-8|language=en}}</ref> By 1998, the brand had grown to 2,500 locations worldwide with $2 billion in annual sales.{{citation needed|date=September 2018}}
