Question:
In the early 2000s, Flash was widely installed on desktop computers, and was commonly used to display interactive web pages, online games, and to playback video and audio content. In 2005, YouTube was founded by former PayPal employees, and it used Flash Player as a means to display compressed video content on the web. Between 2000 and 2010, numerous businesses used Flash-based websites to launch new products, or to create interactive company portals. Notable users include Nike, Hewlett-Packard, Nokia, General Electric, World Wildlife Fund, HBO, Cartoon Network, Disney and Motorola. After Adobe introduced hardware-accelerated 3D for Flash , Flash websites saw a growth of 3D content for product demonstrations and virtual tours. In 2007, YouTube offered videos in HTML5 format to support the iPhone and iPad, which did not support Flash Player. After a controversy with Apple, Adobe stopped developing Flash Player for Mobile, focussing its efforts on Adobe AIR applications and HTML5 animation. In 2015, Google introduced Google Swiffy to convert Flash animation to HTML5, a tool Google would use to automatically convert Flash web ads for mobile devices. In 2015, YouTube switched to HTML5 technology on all devices, however it will preserve the Flash-based video player for older web browsers.

How many years after YouTube was created did it offer videos in HTML5 format as opposed to Flash only?

Answer:
2
Question:
Coming off their Thanksgiving win over their divisional foe, the Lions, the Packers flew to Texas Stadium for a Week 13 Thursday night intraconference duel with the throwback-clad Dallas Cowboys. This match-up would see two 10-1 teams face one another for the first time since 1990 when the New York Giants lost to the San Francisco 49ers. Cowboys quarterback Tony Romo faced off against his boyhood idol Brett Favre in the game. The Packers started the game missing two key players of their defense, with injured cornerback Charles Woodson (tied for 7th in the NFL with 4 interceptions) and pass-rushing end Kabeer Gbaja-Biamila (tied for 6th in the NFL with 9.5 sacks) on the inactive list. In the first quarter, Green Bay took the early lead as rookie kicker Mason Crosby completed a 47-yard field goal. On the first play of the Cowboys opening drive, Al Harris stripped the ball from Terrell Owens and side judge Laird Hayes signaled Green Bay ball, but head linesman Derick Bowers overruled him. The only option for Mike McCarthy to challenge on the play, since the whistle was blown, was whether it was a reception - the strip could not be reviewed. The replay upheld the reception and Dallas retained possession.  Nick Folk completed a 26-yard field goal to tie the game. Folk also completed a 51-yard field goal, and QB Tony Romo threw a 3-yard TD pass to WR Patrick Crayton. The Packers would end the first quarter with rookie RB Ryan Grant running for a 62-yard touchdown. In the second quarter, Dallas responded with Romo completing a 26-yard TD pass to TE Anthony Fasano and a 10-yard TD pass to WR Terrell Owens.  Brett Favre left the game in the second quarter after he hit his right elbow on the helmet of a blitzing Cowboys DB Nate Jones. The throw led to Favre's second interception. Packers quarterback Aaron Rodgers took over for the Packers next series and led the offense on a 74-yard drive, capping it off with an 11-yard TD pass to WR Greg Jennings. In the third, Grant finished off a 69-yard Packer drive with a 1-yard TD run for the only score of the quarter. In the fourth quarter, Romo completed a 4-yard TD pass to Crayton. Mason Crosby kicked a 52-yard field goal with just over 5&#160;minutes remaining in the game to pull the Packers within a field goal. Dallas sealed the win as Folk kicked a 25-yard field goal with 1:03 left in the game. The Packers were flagged for a season-high 142 penalty yards.

How many more field goals were made in the first half than in the second?

Answer:
