Ads generally feature the latest and greatest products from companies all around the world to entice potential customers into buying them. Sometimes, though, companies will use another's product to help push its offer to more people than it would by having a simple ad. The latter ad still typically features new and purchasable products; T-Mobile and Zinio, however, feel differently about online marketing strategies.
The ad you see above is featured on Zinio, a distributor of digital magazines. You can save an amazing 20% on any of your subscriptions of your choice (provided that the titles are in the offer), thanks to a partnership by none other than T-Mobile . . . and the discontinued T-Mobile variant of the Dell Streak 7.
I think it was just an honest mistake by both T-Mobile and Zinio, but for us Streak lovers, it's certainly weird to see our beloved 4G tablet featured posthumously.[Zinio]
