Speculation about Amazon's plans for its TV service, including the possibility that it could launch its own streaming device, has increased ahead of a news conference in New York next week.

The Wall Street Journal reported on Thursday that the online retailer was considering a free, add-supported streaming TV and music service. Amazon spokeswoman Sally Fouts said no such plan was in the works.

"We have a video advertising business that currently offers programs like First Episode Free and ads associated with movie and game trailers, and we're often experimenting with new things," she said in an e-mail on Friday. "But we have no plans to offer a free streaming media service."

Amazon's streaming TV service currently comes included as part of its popular $99-a-year Prime service, which offers unlimited two-day shipping among other perks.
