Many have called 2014 the year of Big Data, meaning that marketers are now numbers-rich, but they are still insight-poor.
Despite the opportunities and efficiencies that Big Data promises to open up, marketers are still being held back from truly unlocking these and moving from big to intelligent data. Marketers have long leveraged data from a huge variety of sources, including transaction data, CRM databases, and market research, to inform strategic and tactical marketing decisions.

Hate Crimes Prevention Act. That law, enacted in memory of two people brutally killed in hate crimes, has generated important police training and outreach to prevent crimes rooted in hate-filled discrimination and bigotry. It also has produced comprehensive statistics — in tandem with the Hate Crime Statistics Act of 1990 — about crimes “that manifest evidence based on race, religion, sexual orientation, or ethnicity,” as well as gender and gender identity.

ICO publishes its report on Big Data and data protection. On 28 July, the ICO released its report ‘Big data and data protection’ (the ‘Report’).
The Report defines ‘Big Data’ and sets out the data protection and privacy issues raised by Big Data, as well as compliance with the UK Data Protection Act 1998 (‘DPA’) in the context of Big Data. The ICO defines Big Data by reference to the Garter IT glossary definition, and further explains that processing personal data must be of a significant volume, variety or velocity. When announcing publication of the Report, Steve Wood, the ICO’s Head of Policy Delivery, stated that “Big Data can work within the established data protection principles….The principles are still fit for purpose but organisations need to innovate when applying them”.
To address these concerns, the ICO recommends several ‘tools for compliance’, including: Privacy Impact Assessments (PIAs) Privacy by Design Promoting transparency through Privacy Notices.

During the 2012 campaign, Barack Obama’s reelection team had an underappreciated asset: Google’s ( GOOG ) executive chairman, Eric Schmidt.
He helped recruit talent, choose technology, and coach the campaign manager, Jim Messina, on the finer points of leading a large organization. “On election night he was in our boiler room in Chicago,” says David Plouffe, then a senior White House adviser. Schmidt had a particular affinity for a group of engineers and statisticians tucked away beneath a disco ball in a darkened corner of the office known as “the Cave.” The data analytics team, led by 30-year-old Dan Wagner, is credited with producing Obama’s surprising 5 million-vote margin of victory.
Schmidt thought enough of the team that when the campaign ended, he put up several million dollars to keep its core together as a new consulting firm, Civis Analytics, run by Wagner and staffed by two dozen of his former employees.
