Mobile is the New "Online"

"Mobile is the new online," says analyst Paul Kedrosky. Mobile is the new ad network, the new data substrate, the new product screen, the new shopping list.

It's rapidly become the currency as well, with people more at peace with turning your mobile phone into your wallet.

But Kedrosky warns there is a serious "scaling" problem with local mobile advertising, namely the cost of reaching local advertisers to sell them programs.

There's definitely a billion-dollar hyper-local ad market but the right way to see it is there's a $15,000 local ad market. There's a whole bunch of many, many small markets.
