Today -- Tuesday, Sept. 1, 2015 -- marks the "Flashpocalypse." Google's Chrome has begun blocking ads using flash, pushing advertisers toward HTLM5, which can work across a wider range of devices, including mobile. Naturally, my inbox has blown up with Flash-focused stories, so I'm beginning to think "Flashpocalypse" refers not to the death of flash advertising, but to the death of an inbox by a thousand pitches.
