Nintendo has also added social networking features to its service. A team of curators will watch the top 100 shows on live TV and post details and a screenshot of important events, such as "a great shot in a basketball game or an unexpected twist in 'Mad Men,'" according to Zach Fountain, director of network business for Nintendo of America.
Users can then comment on these moments and have those posts show up on Nintendo's Miiverse network, as well as Facebook and Twitter if they choose. Users that express emotions could wind up with a sad or happy-looking Mii avatar.
Live sporting events such as pro or college football will also be accompanied by scores and play-by-play summaries on the GamePad's screen.
One problem with the service could be the GamePad's battery life. Nintendo says the controller can be used three to five hours depending on activity and screen brightness before it needs to be charged. But TV ratings agency The Nielsen Co. says the average American watches nearly five hours of TV per day. Heavy users may need to keep the controller plugged in to a wall socket, or buy a $25 battery pack that its maker, Nyko, promises will double the battery life.
