NEW YORK－Bottled water is starting to seem more like soda, and sometimes taste like it, too.

As bottled water surges in popularity, Coke, Pepsi and other companies are using celebrity endorsements, stylish packaging and fancy filtration processes like "reverse osmosis" to sell people on expanding variations of what comes out of the tap. They're also adding flourishes like bubbles, flavors or sweeteners that can blur the lines between what is water and what is soda.

For this year's Super Bowl, PepsiCo even ran an ad for its new Lifewtr, promoting the drink in a spotlight typically reserved for sodas. Also running their first Super Bowl ads were Fiji and Bai Brands, which sell "enhanced waters" made with fruit juice and stevia sweetener.

Michael Simon, Bai's chief marketing officer, says its drinks "give people that healthy profile they're looking for, but now they no longer have to sacrifice on taste with the neutrality of water."

Bottled water has been gaining ground for years, and over-took soda as the No 1 drink in the US by sales volume last year, industry tracker Beverage Marketing Corp said. Some of the fizzy, sweetened drinks are considered water by the companies or industry trackers in some cases, as the distinctions between them lose meaning. Companies aren't as interested in the big, economy packs of plain bottled water that have been fueling the growth, says Ali Dibaj, a Bernstein analyst who covers the industry, since those are less profitable than sodas and are a "horrible business to be in."

So Coke and Pepsi are focusing on pricier options that compete with brands like Evian and Perrier. And they're introducing fizzy and fruity varieties to get a better foothold in increasingly crowded marketplace where options like LaCroix and others are gaining popularity. Showing just how blurry the lines are getting, PepsiCo launched a drink last week that it describes as "sorta juice, sorta soda, sorta sparkling water." Such options can capture people looking to cut back on sodas or juices, and may get people who might buy lower-priced waters to upgrade.

"You can get up the ladder in terms of water and get out of the categories that don't drive a lot of value," Coca-Cola's incoming CEO James Quincey said in September.

Quincey cites Smart water, which has enjoyed sales growth in North America, as a way for Coke to profitably expand its water business. The brand is billed as "vapor distilled" and features actress
