Interest in the PCI Bus is Falling

I was just updating some of the data relating to the PCI Bus yesterday, really just adding some data. There was no new page added.

The main page relating to the Peripheral Component Interface is the PCI Bus Description. Just a few lines of text were added, the real update occurred on the page containing the PCI pin out,[which does not have a page rank?]. I started to add a better description of the signals, and added a few more notes. There are also two additional pages that were updated, each related to PCI card size; Half Sized PCI Board, and Full Sized PCI Board. I guess the only other page is Manufacturers of PCI Boards, but it wasn't updated.

I noted a steep decline in page visits for any of the pages relating to the PCI Interface, by about 4-to-1 over the last three years. Google had data that goes back to 2004, so I posted their graph for PCI Bus searches instead.
The Graph is a Google Trend for the search term PCI Bus.
