In my experience people don't read these large documents because they are not personalized/relevant. When you're writing to a large audience, you naturally assume people know the least amount possible about the subject and start from there. In a corporate setting this comes off as irrelevant or boring. I'm sure rebranding initiatives like One Microsoft, Copilot, or Office 365 makes things simpler for executives but employees are left confused. The memo usually mentions future efficiency gains or synergies but will omit why this brand change is needed. Surely if you're sending a memo to 100k people, it makes sense to not talk about negatives (a good example of this is politicians) but at that point the value of memo is also very low. This may come off as odd but short format videos seem to work much better at large scale. Perhaps the future of communication is really just lots of easy to consume/repeated content.
