The CEO, whose screeching and dancing at company events is the stuff of YouTube legend, stormed the stage to Cant Hold Us by Seattle rap/producer duo Macklemore and Ryan Lewis, and kept up his usual high tempo, according to several people present at the employee-only meeting on Thursday.
He departed to the strains of Michael Jacksons Wanna Be Startin Somethin, the song played at Microsofts first employee meeting in 1983, followed by (Ive Had) The Time of My Life from the finale of Dirty Dancing, getting a standing ovation from the 13,000 or so Microsoft full-time employees in attendance.
We have unbelievable potential in front of us, we have an unbelievable destiny, said a visibly moved Steve Ballmer, reusing a quote from the 1983 meeting. Only our company and a handful of others are poised to write the future, he continued. Were going to think big, were going to bet big.
Steve Ballmer, who announced his plan to retire within 12 months in August, was the last act of the all-day event at Seattles KeyArena, former home of the citys SuperSonics basketball team.
Thousands of full-time Microsoft employees showed up, most of them bussed in from Microsofts campus on the east side of Lake Washington while an estimated 25,000 more tuned in via webcast.
The event is an annual traffic nightmare for Seattle, with 220 buses making the 25-kilometre journey from Microsofts campus in Redmond to the centre of the city.
During his time on stage, Steve Ballmer talked about telling his parents about deciding to drop out of Stanfords business school to join Microsoft on 1980, recalling that his father a long-time Ford Motor executive asked him what a personal computer was.
He dwelt on his new plan to transform the company from a software-centric operation into a more innovative devices and services company, which he said would make it fundamentally more powerful.
He also took a swipe at rivals, declaring that Apple is about being fashionable, Amazon.com is about being cheap, Google is about knowing more, but Microsoft is about doing more.
Microsoft has a bright future, Steve Ballmer said, echoing his theme from last weeks meeting with Wall Street analysts.
