Nasdaq-quoted Nvidia's GeForce product line is a core technology in Microsoft's Xbox gaming console.
The firm has also worked with Microsoft on the graphics for the upcoming Windows Vista platform (see Related Stories) and provides the graphics processor in Sony's PlayStation 3 console. Nvidia also makes hardware for consumers to upgrade their existing systems.
Its UK account had been split between Wildfire and Prodigy Communications.
Liberty senior account manager Nikki Hutchinson left her account manager role at Wildfire to join Liberty in July.
Liberty head of consumer tech is director Mark Casey, who joined from Prodigy - which he co-founded - this summer (PRWeek, 8 June).
‘We felt that Nikki added tremendous value to the account and we've built an excellent relationship with her,' said Nvidia corporate comms manager Bea Longworth.
‘As a result of her move, we invited both Liberty and Wildfire to repitch. With Mark being ex-Prodigy, we just felt Liberty offered us the best of both worlds.'
Prodigy, which has just closed after seven years (PRWeek, 13 October) handled a much smaller part of the account.
‘We had a great time working with Nvidia and believe we fulfilled the brief it gave us a year ago,' said Wildfire MD Debby Penton. ‘We ended on good terms and wish them all the best.'
Liberty is to handle B2B, corporate and consumer comms for Nvidia.
‘We will focus on raising the corporate profile of Nvidia, which is that of a market leader, in the UK by targeting the financial press,' said Casey. ‘For the B2B work, we will concentrate on developing channels to market.'
