It used to be so simple. Media aggregated audiences (eyeballs) brands advertised and retailers fulfilled the demand with store shelves and products.But increasingly these lines are blurred, and will soon be gone.No longer will people consume content from one source, be exposed to ads, and then be directed to a destination to act.Content and Commerce will merge into single destinations.Which puts ecommerce companies and brands on notice, they need to become content destinations quickly. To survive, the mantra must be publish or perish. The challenge in a noisy world is to evolve from the last stop on the journey to being the first.Examples range from consumer electronics, to financial services, to clothing and footware.What you'll see is that some of the folks who historically have paid for advertisements, have decided that in order to survive and thrive in this new world they need to go from Buying Media to Being Media.B&amp;H Photo&#8217;s World of Photography - Shop.

The curation changes from month to month. Crowd sourcing content from a brands trusted circle of employees and friends is content creation that is both authentic and low cost. Clothing is all about community, and being part of a trend and style. Club Monaco is able to invite their customers to participate - and enjoy being part of a quality curated experience.Overall, the thing we're seeing is that the line between media and brands is blurring. The web's speed, and the turn over of content requires new content creation solutions for brands. &#8220;The Internet has a very short attention span, and it cannot be maintained. One moment you have people's attention, and in the next they've moved onto a video of a kitten sliding on the kitchen floor,&#8221; says Nuno Ferreira, vice-president and creative director at Leo Burnett.Publish or Perish.
