In 1999, the Promus Hotel Corporation was bought by Hilton Worldwide for $3.7 billion. In 2004, as part of the $100 million "Make it Hampton" initiative, Hampton began upgrading its hotels including the production of an alarm clock which featured an easy-to-set alarm and an mp3 player hook-up. Other changes made during the upgrade were the switch to white bedding, adding hot food items to continental breakfast options and free high-speed internet to rooms. In 2012, under the "Perfect Mix" initiative, the company completed upgrades to the lobbies of its hotels adding more social space. Hampton continued to renovate its spaces with a campaign introduced in 2013, directed towards younger clientele that included in-room mini-fridges, new bedside tables with power access, updated bathrooms, and updated hotel exteriors. Hampton by Hilton has been ranked in the top 5 in "Entrepreneur"'s Franchise 500 from 2010-2015.
