Mashable was created by Pete Cashmore from his home in Aberdeen, Scotland, in July 2005. Time noted Mashable as one of the 25 best blogs in 2009. As of November 2015, it has over 6,000,000 Twitter followers and over 3,200,000 fans on Facebook. In June 2016, it acquired YouTube channel CineFix from Whalerock Industries.
In December 2017, Ziff Davis bought Mashable for $50 million. Mashable was not meeting its advertising targets, and was losing money, with $4.2 million losses in the quarter ending September 2017. After the sale, Mashable laid off 50 staffers, although Ziff Davis insisted on keeping top management. Because of the drop in value, stock options issued to employees during Mashable's successful times were worthless.
