Flash is a true child of the 90s: Excessive, unwieldy and self-indulgent.
Seemingly overnight, otherwise normal sites were suddenly bristling with motion effects, even those that had resisted the previous onslaught of animated gifs.
And nowhere was this phenomenon manifested more frequently than the animated splash page.
Given the limits on bandwidth in these early days of the internet (I was still on dial-up when Flash was first released!) it's incredible that we thought it a worthwhile use of our data.
In truth, splash pages of any kind have never been worth the cost.
We don't measure that cost in bandwidth however.
