I highly doubt Pentium was at risk of becoming a genericized trademark...

Google quite possibly could... point is that intel has managed a brand, and managed it very effectively...

Pentium wasnt quickly phased out? they used it from 1993 until 2008... they did try to phase it out to create a new brand for multicore processes but OEM manufacturers wanted them to keep the brand because it meant computer sales, so pentium stuck for another 2 years on dual-core cpu's
