The three rising giants of tech all spent heavily on K Street in the first quarter of the year, marking perhaps a permanent change in the hierarchy of Silicon Valley's profile in Washington. Google, the search giant whose lobbying has sprawled into every corner of Washington as it has expanded into new ventures, spent $5.47 million on federal lobbying in the first three months of 2015 - awfully close to the record $5.5 million it paid out in the second quarter of 2014 and more than it has spent in the first quarter of any year, including 2012, when it posted $5.41 million in payments.
