I've often commented that it wasn't that IBM culture didn't have interactive development ... which was compareable to features/size of most other vendors (that might be considered interactive) ... it was that in the 60s, 70s & much of the 80s, the batch market size dwarfed the interactive.

in afc ng ... i've often mentioned that the number of vm/43xx customer installs were larger than vax/vms installs ... in part because some number of large customers would order then in blocks of 100s at a time (i don't believer there were ever any single vax/vms orders for 1000 machines ... until possibly you got to microvax). misc. old email discussing 43xx activity

internally ... all the original relational/sql work was done on vm ... lots of past system/r posts
http://www.garlic.com/~lynn/subtopic.html#systemr

and the internal network was larger than the (whole) internet/arpanet from just about the beginning until sometime mid-85 ... and was nearly all vm machines. misc. past internal network postings http://www.garlic.com/~lynn/subnetwork.html#internalnet

one of my hobbies was building and supporting highly modified custom operating system for internal distribution. i've periodically joked that the number of customer batch systems were much larger than the number of customer vm systems. the number of customer vm systems were much larger than the total number of internal vm systems. the total number of internal vm systems were much larger than the peak number of internal vm systems that i provided distribution and support for. however, that peak number (that i directly built, distributed, etc) was still as large as the total number of multics systems that ever existed. this comparison was somewhat because the vm stuff had started on the 4th flr of 545 tech sq ... and the multics stuff was on the 5th flr ... misc. past posts about science center and 545 tech sq

in the early 80s ... bitnet/earn for a time was compareable in size to internet. bitnet/earn was based on similar vm technology used in the internal network ... but totally different network http://www.garlic.com/~lynn/subnetwork.html#bitnet

it wasn't that the IBM culture involved in interactive was smaller than other vendors interactive activity ... it was that the batch market acitivty was so much larger, that skewed perception.
