A few grammatical errors aside it looks alright to me. But I'd point out the international depression was also a thing immediately after the war and would have been a more direct component of the post-war events earlier on than your history seems to imply, with it happening a few years after; as it's also directly related to the massive cut in military expenditures and the industrial demands to keep the first world war rolling. But that may be an issue of presentation of misplacing it in the time-line of events.

I might also comment on the lack of things happening in the interim of the twenties till now, but that may be asking for more than we'd need right now and can certainly be explored later.

And of also proper mention: television wouldn't have been a wide-spread or even notable thing in the 1920's, let alone the late 1920's. At best maybe there'd be newsreel footage dispatched to theaters around the nation for televised mass-media. But the newspapers are just as likely to be able to publish articles on something the day after or in the following days for daily readers; if not then the radio is the biggest contemporary broadcaster. Even if we ignore alternate history implications television only became accessible on a large scale until the fifties or sixties; it should only be experimental now.
