It used to be you had to go all the way to Las Vegas to play the slots. But soon, you may be able to gamble on your smartphone.

Thanks to improvements in technology, a change in federal rules and shifting political calculations, a push to legalize online and mobile gambling is picking up steam. Three states already have moved to allow it, and Silicon Valley tech companies, including San Francisco-based social gaming giant Zynga, are rushing to cash in.

"It's inevitable that this spreads pretty quickly," said Doug Walker, who studies casino gambling as a professor of economics at the College of Charleston in South Carolina.

Last month, the governors

of New Jersey and Nevada signed laws to legalize online gambling in their states. And earlier this year, Delaware, which legalized online gambling last summer, solicited bids from companies to run the service that will oversee online gambling there.

Similar legalization proposals are being promoted in numerous other states, many of which are searching for new revenue to replace tax dollars wiped out by the Great Recession. In California, state Sen. Roderick Wright, D-Inglewood, has introduced a bill that would legalize all online gambling in the state, while state Sen. Lou Correa, D-Santa Ana, has proposed a bill that would legalize only online poker.

It's not just cash-strapped state governments that see a potential jackpot in

online gambling. Casino operators and Silicon Valley tech firms are also pushing for legalization. Zynga, for example, is already moving to offer online gambling in the United Kingdom and Nevada.

Legalization proponents argue that many consumers already gamble online through offshore sites. By legalizing the activity, they say, states can tax and regulate it -- and U.S. companies can benefit.

"Prohibition, like the prohibition of alcohol, just doesn't work," said Joseph Kelly, a professor at Buffalo State College in New York who has consulted with governments outside the United States that have considered legalizing online gambling. "I like to think of (legalization) as recapturing revenues."

But gambling opponents, consumer advocates and addiction researchers warn of potentially dire consequences. They say the gaming industry will use techniques perfected in online advertising and marketing to target vulnerable consumers, leading to a spike in problem gambling and, more broadly, a rise in income inequality.

"This is the most predatory business in the country," said Les Bernal, national director of Stop Predatory Gambling, a nonprofit group opposed to commercial and state-sponsored gambling. "They're

about creating new players and getting them to be out of control."

Until little more than a year ago, much of the discussion about online gambling in the political realm was about banning it. But in late 2011, the U.S. Department of Justice revised its interpretation of the Federal Wire Act, a law designed to combat organized crime. The Justice Department determined that instead of banning all online gambling, the law applied only to sports betting.

The change allows states to legalize Internet gaming within their boundaries. But it potentially could also allow citizens from one state to gamble on Web or mobile sites hosted in another state, if the two states come up with an agreement to permit the practice. In the meantime, Congress has been considering a measure that would legalize interstate online gambling in whichever states authorize it.
