UPDATE 2-Wall Street Journal to charge mobile readers

* Wall Street Journal to soon charge for mobile news

* Nonsubscribers to pay $2/week; Subscribers pay $1/week

* Murdoch says advertising environment "very much better" (Adds details about pricing, advertising and Hulu)

NEW YORK, Sept 15 (Reuters) - The Wall Street Journal soon will begin charging people to read the paper on mobile devices such as their BlackBerrys, the paper's owner Rupert Murdoch said on Tuesday.

The move, which News Corp (NWSA.O: Quote, Profile, Research) CEO Murdoch announced at a Goldman Sachs conference in New York, is an attempt to find a new way for the business daily to make more money from an increasingly popular way for people to access their news.

The Journal will start charging for mobile access "in one to two months," Murdoch said.

Under the plan, people who do not subscribe to the Journal would pay $2 a week for mobile access, and subscribers would pay $1 per week. Subscribers to both the print and online version of the paper will get mobile for free.

Charging for mobile access is one of the boldest ways yet that a U.S. newspaper has tried to increase revenue, at a time when falling circulation and print advertising revenue is threatening the survival of many newspapers.

The Wall Street Journal is one of the few U.S. newspapers that has successfully charged for access to news on the Internet.
