Consumers preparing to buy or change a wireline service -- whether it's broadband, phone, cable TV, or streaming video -- are increasingly using mobile devices to do their shopping, according to research released today by Google. And people looking for customer service increasingly turn to video services such as YouTube Inc. for help.

Google (Nasdaq: GOOG) said the research is meant to help wireline service providers understand buying habits. However, the results clearly bolster online search and video services as primary means of reaching consumers -- a message that promotes what Google has to sell.

The good news for wireline service providers is that the market is growing. Google reports a 14 percent increase in people who plan to buy a service and a 48 percent increase among those planning not to cancel a service. (Those numbers weren't broken out by service type.) The biggest growth factor, Google said, is less service switching. Only 18 percent of those surveyed said they were switching service providers, versus 26 percent last year.

"Our research does not look specifically at why this is happening, but we do suspect that the positive economic outlook -- consumer confidence, lower unemployment -- has something to do with fewer people dropping providers just to save money," Kyle Keogh, industry director of technology for Google, told us in an email.

Still, 41 percent of those getting a new service cited price as a major factor, and 73 percent of all respondents called price an "extremely important" consideration; 68 percent said that about reliability.

Here are some other findings.
