First off, the fact the adverts exist doesn't mean there was lots of advertising. Like I said, when are those ads actually on? (I can only speak from the UK).
I don't think you're putting enough stock in advertising. Perhaps it's because I'm involved branding/advertising that I'm seeing its importance here. Occasionally, advertising alone can turn something around. and I'm not just talking about a change in advertising, I'm talking about going from zero brand awareness to....well a lot more brand awareness hopefully.
I'm not saying there is no value in advertising.
I disagree there is "no awareness" of this product. It was launched at the height of the shopping season. It was in ample supply. It has the Wii brand and a Mario game. In the UK ads were apparently aired during X-Factor. I also don't really think either of our subjective anecdotal experiences of advertising amount to conclusions on whether or not the product has been advertised.
I fail to see how advertising the value proposition on offer, as it was and as it currently is, would yield dramatically improved sales performance.
There isn't always a real need for a product, that's the point in advertising: convincing a consumer that your product is essential. Worse products have succeeded, better products have failed. Correctly strategising your advertising and branding is hugely more important than you are implying imo.
A product has to address some underlying want or need - especially one that requires a relatively significant amount of money for families on limited budgets. Market validation is the cornerstone of successful product launches. Advertising can promote a value proposition, but it doesn't create one out of thin air.
In the post quoted I asked you why exactly, whence made aware of the value proposition (on the assumption that people are not aware) there would suddenly be demand for it. The question was left unanswered.
Why does the mother of two care about a tablet controller and "asymmetric gameplay"?
Why should the college student care about "off-TV play"?
Why does the teenager who already has a 360 want a Wii U with it's marginal performance improvement over his current system?
With Vita, there was at least a tonne of awareness. Maybe they still didn't market it correctly though.
We must have been watching a different product launch. I really didn't see a "tonne of awareness." The Vita, the successor of a failed handheld in the US market, was essentially sent out to die. But again, I don't think subjective anecdotes and opinions on the degree of marketing amount to much, and I don't think the fundamental problem with Vita was marketing either. It was a product aimed at a market that wasn't there (as opposed to the Wii U, which frankly has no real focused target market.)
