Following decades of slow movement due to cable companies facing no competition, the television world is changing rapidly. Lots of challengers have arisen in the pay-TV space in recent years.

Ajit Pai, the new chairman of the Federal Communications Commission, last week issued a call for activation of the FM chips in smartphones. The vast majority of smartphones sold in the U.S. have FM chips, but they're activated in only about 44 percent of the top brands, Pai said. Although that's nearly twice the 25 percent figure of two years ago, it's not good enough, he suggested.

Customers and investors increasingly are wondering why Verizon and Verizon Wireless are hurting themselves with their actions.
