More than a year of work to bring Amazon.com Inc.¡¯s headquarters and tens of thousands of jobs to New York City ended on Thursday with a couple of phone calls.

Jay Carney, the company¡¯s top policy executive, told New York Gov. Andrew Cuomo that the world¡¯s biggest online retailer would not go ahead with plans to invest $2.5 billion (about ?276 billion) to build a second head office in the borough of Queens.

Carney, a former press secretary for President Barack Obama, told New York City Mayor Bill de Blasio the same shortly after.
