Well, in short, no one really knows. I know thats obvious right ?
However, if I was a betting girl, I would say March is your month for the hard stuff.
Mainly, for three reasons. The numbers (date ranges - milestones-NASDAQ-economy in the US)tell me so. The degree of placements, severity or veracity of teaser number two, and its overall message fit with teaser one. Third, you really want to ramp in spring and be red hot before summer, and risk losing momentum. Once summer comes, much of your marketing mo-mo has or may or even "can" dissapate. After summer comes fall, baseball world series, new tv schedule, thanksgiving, Christmas. If you want the hearts and minds....do it into spring and early summer and then its easier to keep the interest.
