Passage: Digital distribution of movies has the potential to save money for film distributors.  To print an 80-minute feature film can cost US$1,500 to $2,500, so making thousands of prints for a wide-release movie can cost millions of dollars. In contrast, at the maximum 250 megabit-per-second data rate (as defined by Digital Cinema Initiatives for digital cinema), a feature-length movie can be stored on an Commercial off-the-shelf 300 Gigabyte hard drive for $50 and a broad release of 4000 digital prints might cost $200,000. In addition hard drives can be returned to distributors for reuse. With several hundred movies distributed every year, the industry saves billions of dollars. The digital-cinema roll-out was stalled by the slow pace at which exhibitors acquired digital projectors, since the savings would be seen not by themselves but by distribution companies. The Virtual Print Fee model was created to address this by passing some of the saving on to the cinemas. As a consequence of the rapid conversion to digital projection, the number of theatrical releases exhibited on film is dwindling. As of 4 May 2014, 37,711 screens (out of a total of 40,048 screens) in the United States have been converted to digital, 3,013 screens in Canada have been converted, and 79,043 screens internationally have been converted.
Question: As of 4 May 2014, how many screens world-wide have been converted to digital?
answer:
number

Passage: Trying to snap a two-game skid, the 49ers stayed at home for a Saturday night interconference battle with the Cincinnati Bengals.  With QB Trent Dilfer out with an injury, back-up Shaun Hill would be making his first career start. After a scoreless first quarter, the Niners drew first blood in the second quarter as Hill got a 3-yard TD run.  However, the Bengals would take the lead as kicker Shayne Graham managed to get a 24-yard field goal, while QB Carson Palmer completed a 52-yard TD pass to WR Chris Henry.  The Niners would end the half as Hill completed a 17-yard TD pass to TE Vernon Davis. In the third quarter, San Francisco increased their lead with kicker Joe Nedney managing to get a 29-yard and a 38-yard  field goal.  In the fourth quarter, Cincinnati tried to mount a comeback as Graham kicked a 35-yard field goal.  Fortunately, the Niners' defense held on for the impressive victory.
