buying space for advertising in tv shows and movies works well if you have something new/innovative (think of the communicator in James Bond) to push, but the problem with WP is it doesn't offer anything new.
the one thing it does offer is consistency.
MS have consistently offered mobile platforms that don't support older hardware, provide nothing new (in fact, often less features than the competition) and fail to provide an upgrade path on existing hardware.
Akin to the XP to Vista Fiasco, untold large organisations have chosen to stick with older versions of winmo simply because the new versions are a downgrade in terms of application compatibility and featureset.
MS have also consistently told users that the current issues "will be fixed in the next release/version".
Australia has seen a massive push in advertising for the Lumia line, and yet speaking with sales people (both operators and even stand alone retailers) in the industry, they call it "boring" and lacking in features.
Now why would you try to sell to a customer base that competition demands you need to retain, a product that risks alienating them?
And Nokia jumped into bed with this?
