You're probably right about what advertisers (and possibly magazine publishers) are thinking, but this is the way web pages have gone, and in my opinion many websites are nearly completely unusable because of all that "glitter." It may be the case that many digital magazines will end up looking like those websites.
Then again, I can see the value of publishing a magazine like MAKE or Scientific American with some video or animation to illustrate complex processes or ideas. Some non-fiction books might use this to good advantage, too. (E.g. Stephen Hawking's
A Brief History of Time.)
But I still say, I read fiction, I like reading fiction, I don't want noise and movement in my fiction, and I think I'm not the only one!
Ok, I'll calm down now. I'll just go make a pot of tea, shall I?
