It’s time for another episode of Mobile Biz Buzz with new host John “jaQ” Andrews!

Key takeaways from this video:

  • Mobile devices are spreading faster than older technologies did.
  • Samsung’s Smart App Challenge 2012 offers more than $4 million in prizes to developers.
  • SHAPES+ offers virtual interactive games teaching colors, numbers, and shapes.

An MIT Technology Review study found that tablets reached 10 percent of the U.S. population in just three years. Older technologies like radio, television, and cell phones took more than twice that long to get a similar foothold.

Smartphones also grew quickly. Once they hit that 10 percent threshold, they reached “maturity,” or 40 percent market penetration, in only three years. Now, about two-thirds of all mobile phone sales in the U.S. are smart phones.

Samsung has launched the Smart App Challenge 2012 to encourage development for its Galaxy Note and Galaxy Tab devices. The contest runs through September 30 and offers a total of more than $4 million in cash as well as marketing support to 80 apps.

The grand prize winners in three categories will each take home $200,000 and be promoted through Samsung press releases, social media, television and print ads, and other marketing channels.

This episode’s App Feature is SHAPES+, an iPad app available for $4.99 in the App Store. It teaches colors, numbers, and shapes through interactive games and exercises.
