The EU said Monday it wanted tighter rules to regulate the fast developing online gambling industry in an effort to better protect minors and coordinate a huge but fragmented market. European Union data shows that in 2012, seven million Europeans gambled online, making up a huge 45-percent share of the world market, which according to industry data, was worth $33 billion (24 billion euros) that year. The explosion in European online gambling began in a smaller group of member states, including Britain and Malta, where companies flourished, drawing in gamblers from around the world. Other member states — such as France and the Netherlands — for many years delayed growth, keen to not only protect consumers but lucrative state gambling monopolies as well.
