Was it ever stated exatly where it should begin?

And considering that the only episode I hate is early season 1 and my two most favourite are season 2 (one being the newest, Candace's Big Day), I don't think Phineas and Ferb may loose their jazz. It's just that when you're making a story it's impossible to please everybody.
