It won’t respond. Yelling louder isn’t the answer. Constantly experimenting with different ideas will force the market to pay attention. The market won’t respond if you start advertising an old product in a new world (dramatic changes can now take places months at a time). Instead of working what you have and getting the same result, try a different approach. Create another product, or use something differently.
If the market isn’t responding, you’re doing something wrong. Yelling louder in the middle of a desert attracts the same amount of people as a whisper–none. In order to get the market to respond, you need to change. When you change, the market will respond, and soon enough, there will be people who couldn’t imagine what would happen if you weren’t around.
