Hi guys,
Just wanted to add my 2 cents into the discussion.
I’m a front-end developer who works in a large advertising agency and primarily create html animated display ads & digital screen signage for our clients.
I’ve been working in web design since '95 and used to use Flash when it was big, followed by Greensock JS up until about 3 years ago when I switched to Hype which is fantastic.
I’ve seen an increase in animated html display ads over the last couple of years so think the OP may have just had a blip with their clients. Display ads are big business and we go through huge amounts of them in our studio to supplement large campaigns for major clients.
Hype is a brilliant tool for allowing me to very quickly create animated html and export to various network specifications. Looking forward to seeing the program grow in the future.
