One simple chart shows how retail as we knew it is dying

Retail companies are in the middle of a seismic shift.

Younger shoppers are taking over the market, and they have a penchant for online shopping. This means that older, brick-and-mortar sellers are struggling to keep up with online giants like Amazon.

Home-products maker Procter & Gamble - think Tide detergent and Pampers diapers - laid out in one simple bar chart just how huge this shift has been.

The slide, from a company presentation at an analyst conference this week, shows the monthly buying frequency of US shoppers in hypermarkets - stores with both grocery and department sections - and online.

In just seven years, shoppers have shifted from making one monthly purchase on average online, to 6.5. Meanwhile, purchases at brick-and-mortar stores dropped from 7 visits to just under 5.

But even as traditional retailers adapt to the shift, they face the issue of added costs, which crunch profits.
