Mark McClusky says for elite athletes today, pushing boundaries and breaking records is all about "the aggregation of marginal gains."
As more Americans opt for smartphones, telecom companies like Verizon and AT&T are getting a huge boost from the data plans they’re selling. Telecoms have seen revenue for data plans increase by $38 billion over four years.
And that’s translating into dramatically higher cell phone bills. Last year, some families with four smartphones spent more than $4,000 to stay connected.
That figure has been rising for the past four years.
But as families increase the amount of money they spend on cell phone service, they’re cutting back in other areas, like eating out, clothes and entertainment.
And economic experts say that shift in spending is hurting the bottom line of restaurants, clothing stores and the film industry.
