Perhaps there's no answer to this, or it's obvious and I ought to know.
How can I find out when ARIN or the applicable registry has assigned a block
to a certain organization, and I don't know the block, just the
organization.
If that's not possible, is there a site/way that has a timeline for the
first time a certain AS announced a block?

Frank,
Add the > operator in front of the organizations ARIN ID when you do your WHOIS query and it will show all of the resources allocated to that organization.
Those are both very simple reports to run from PCH's existing databases
and data-feeds. The only tricky part is how you specify the organization
name... Are you planning on using the RIR OrgID, or an exact-match on the
organization name, or a substring or regex match? Or would you like
something that tries to map through origin AS?

By that, I mean that they could be run daily, and specific results emailed
to people who were interested in following the allocation patterns for
specific organizations, any time there was a match.
-Bill
When I do that it lists the organization's AS, but not any netblocks
associated with that AS.

Following up on my own post for the second time tells me that I'm posting
too early in the morning, or without the recommended seven-second
broadcast delay between brain and fingers, but... My colleagues have
reminded me that we already built this system two years ago, and it
produces an RSS feed, rather than email results. Also, that we hadn't
done as much as we should do to provide filtering tools to narrow down the
results. So, two questions for the community:
1) Would people prefer to receive these results via email, or RSS, or
some other mechanism?
2) What would the structure of the query or filter look like, ideally?
What key would you like to be querying on, and how would you like
the results focused?
-Bill
Ok, so not so simple. =)
I'm not familiar with the layout of PCH's data (I did find some .gz files,
so I presume that's the data that's gathered on a daily basis), but if I
was, I would have to take the divide-and-conquer approach for a certain AS
to find out when a block was first announced.
I'm guessing that I would have to do the hard work. Perhaps Renesys is
already doing this? (but for a fee).

No problem, I had my coffee 2 hours ago.
1) I would prefer e-mail, and ideally on-demand querying from a web form.
And even more pie in the sky, something like Google Trends (i.e.
http://www.google.com/trends?q=hurricane+katrina&ctab=0&geo=all&date=all)
that shows the quantity of IP addresses that are being advertised over time.
2) Basically I would sign up for certain AS' and be informed when new blocks
are added, or when blocks stop being advertised (for a full 24-hour period,
I don't think there's value in seeing when it's withdrawn and re-advertised
in one day). There might be some people that want to know when a block is
first advertised, but that's less likely unless they're tracking the
de-BOGON announcements.

Frank

Keep in mind that the "> OrgID" trick only works for allocations or assignments made directly by ARIN; it won't necessarily show you everything that was SWIPed to them, since many SWIPs are not tagged with an OrgID. To find those, you have to search on the name of the customer and hope it shows up correctly in the CustName field.
Also, many companies end up with lots of OrgIDs, and many of them may not have the correct current name due to M&A activity. Finding them all may take a while and isn't easily automated.
