If you are new to the industry or just want to learn more about 3D graphics applications, I just published a guide that you may find interesting. It's a look at all of the 3D applications in use today, with a bit of a history lesson thrown in. For even more detail/info, there is an hour long video as well.
So if you are just starting out and trying to figure out what to learn, or are just interested in CG in general, I hope this proves useful. If you are a vet, I would love to hear your opinion or let me know if you think I missed anything important.
