Pleon consumer director Eva Keogan said: 'The "Is it live or is it Memorex?" brand positioning is well established. Memorex has rebranded globally, so it is a good time to be on board.'
The firm has revamped its logo and put more focus on online music and video reproduction. Pleon takes over from Spreckley Partners on the brief, understood to be worth at least £100,000.
Sister agency Brodeur represents Memorex in the US and Canada.
