Where can I see the chronology of the development of CISCO routers?

Question

Cisco

I would like to see the history of cisco network equipment (mainly routers) in any convenient form. Type range, features, modifications. I googled and didn't find anything at all.
The hardware of any other major network vendors will also be interesting.
