Digitas CEO David Kenny said the agency's relationship with key client General Motors remains strong despite the departure of key executive Jack Bowen, the carmaker's director of consumer relationship management, reports AdWeek. Digitas also reported that fee revenue for the third quarter was $85.5 million, up 43 percent from last year's third quarter, though net income fell slightly because of a $3.2 million bad-debt expense resulting from Delta Air Lines' bankruptcy. Earnings for the quarter were $8 million, down slightly from $8.2 million in the year-ago period.
