product names

The infinite monkey theorem seems to apply to the drug (and other) company product names I see advertised on television. There is a problem though. Without adding additional letters to the alphabet, every combination of letters will be exhausted. There are just so many ways to arrange the letters to form new names for inane drugs. It's a finite universe of choices. Possibly, using various numbers sprinkled willy-hilly might be the answer to the looming problem. That would allow the various company names and products to continue forever. Okay! Problem solved!
