Two smart moves by two smart giants in the subscription industry.One, National Geographic has teamed up with Epic eBooks,  to make its eBook titles available to more children through Epic’s iPhone and iPad apps. National Geographic will be offering titles like Dog Finds Lost Dolphins from the popular National Geographic Kids Chapters series, Sharks from the leveled National Geographic Kids Readers series, and other fun titles like Myths Busted.The move is smart one for both publications. While there will likely always be a place for print storybooks, especially at bedtime, younger generations are already acclimated to the digital environment, and National Geographic needs to meet its younger audience where they are. For Epic, snagging NatGeo is likely to lend more credibility to the growing start-up, not to mention augment the services offerings and, in turn, profits.Meanwhile, LinkedIn just bought Newsle, a service that pings you when your friends and acquaintances make the news.LinkedIn has already begun sending emails to members when people in their network are covered in the news, but the Newsle algorithm will likely help them strengthen and grow that technology.The exact terms of the deal were not disclosed, nor does there seem to be a timeframe for the integration. But Newsle has amassed 2 million users since it first launched three years ago and has raised $2.6 million to date, making it a smart buy for LinkedIn.
