What advertising agencies do US companies LA Fitness (NOT UK company with same name) and 24 Hour Fitness use?

Question

I need to find this information out about the US companies not the UK ones. They are separate companies. I need to know who the advertising agencies are for LA Fitness (USA) and 24 Hour Fitness (USA).

Answer 1

The source you want is the Agency Redbook.  You might check whether your local library has it in its business reference section.  Otherwise it would cost you $2K to buy it.
