@Todd: Max, how about links to the originals of the maps?
If you go to www.Google.com and select the "Images" option and then search for "Dr Who Timeline" you will see the ones I talked about plus a whole lot more.
Similarly, if you search for "River Song Timeline" you will see the ones I talked about plus a bunch more (I also like this one -- plus this article and two associated graphics are interesting, especially since it was before we actually discovered who River Song is/was.
I envy you that, in all probability you were in the right place and time to see the only broadcast of the 79 or o "Lost" or destroyed episodes.
It does make the value of backups more apparent. If it was not for the popularity of the show, none of the Black and White episodes from the 1960s would survive. That we do have most of them back only makes the ones that are not all the more poignant.

What is missing are the actual visual performances, By some of the forgotten greats of British theater.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
