The "TPM" you know today started life as Microsoft Palladium, an attempt by Microsoft to create a hardware DRM implementation for "content producers" that could tell the OS what was allowed and not allowed on your computer. The assumed goal at the time was that once the frog was sufficiently boiled it would be used to enforce Windows licensing as well. After much backlash they diverted their efforts into a cabal with Compaq, HP, IBM, and Intel to make it more general purpose and actually allow the end user to store keys. Secure boot was mostly just a toy until Google implemented it in Chromebooks and the large customers you speak of pointed and said "I want that!"
