Thanks to Steve Souders (who works for Google), significant data shows that among the top 17 000 websites there was a 2 percent drop in Flash usage, in just over 4 months. You may consider that to be a small drop. But 2 points over such a short period of time is actually significant especially in the website industry, that in many cases, takes about 3 or 4 months to think about changing something...
Not great news for traditional Ad agencies that love Flash and have strong Flash development skills. But good news for the companies that are focusing on HTML5 and a more multi-platform compliancy approach...
