International Business Machines Corp. said it hired an agency formed by several defectors from IBM’s prime advertising agency to create a single ad for its new line of personal computers. IBM, however, said it has not taken its annual $125-million personal computer account away from Lord, Geller, Federico, Einstein, which is now part of WPP Group PLC. For nine years, Lord Geller has handled all of IBM’s personal computer advertising. Lord Geller has been in turmoil since March when its founder, Richard Lord, and other key personnel resigned to form a new company, Lord, Einstein, O’Neill & Partners.
