TT 2010 was officially launched in March with a revamped entertainment programme and new website.
Fans around the world were able to follow the motorbike action free of charge with access to live commentary and timings via the official website www.iomtt.com run by Duke Marketing.
Managing director Peter Duke said: "We are delighted to retain the management contract for the official TT website following the recent competitive tendering process.
"As we approach the two million visitors per year milestone it's great to keep moving the site forward with new and improved features so it delivers more and more of what the modern TT fan requires - whether visiting the Island or not."
After facing heavy criticism in 2009 over the entertainment during the TT period organisers pulled out all the stops to make TT 2010 one to remember.
Entertainment over the week included comics Ross Noble and Al Murray, a classic bike night, displays by the Purple Helmets and the White Helmets. The funfair returned to Douglas Promenade and there was a film zone at Broadway Cinema. The week ended with a firework display over Douglas Bay.
Tourism and Leisure Minister Martyn Quayle MHK said: "We wanted to create an action-packed festival with lots of activities that would appeal to both our visitors and residents.
"We have also looked to create plenty to do for people of all ages and believe that we have high quality entertainment that will live long in the memory and will perfectly complement the high standard of racing that we now have."
On the racing front the solo entry class saw 11 former winners and 50 riders who had already lapped in excess of 120mph sign up. The Formula 2 Sidecar class contained three world champions and nine crews which have lapped the Mountain Course in excess of 110mph.
