Bloomberg's ads are slightly separate from their regular ads; the "other content" is still news most of the time - Bloomberg is at its heart a data and news feed company (the video news is mostly an add-on for them), so they are doing what they do best anyway. "Idiocracy" is an interesting example; while the style is similar, the side content on BTV, while a pale shadow of the actual terminal, is actually quite information-rich (especially on BTV+); the actual terminal is entirely populated by feed/data/whatever function you're using.

I am on an iPhone SE 3rd gen. due to the small form factor. It is already annoying to surf the web even with an adblocker, lots of cookie banners, notes, requests to install app/signup etc. take so much screen space that you can see no content. Clearly developers do not test or care for small screens anymore.
