Online content pioneer Mark Cuban told the Senate Antitrust Subcommittee Wednesday (Dec. 7) that the AT&T-Time Warner merger is pro-consumer and will be necessary for the companies going forward to be competitive with the dominant content providers, Web content giants Amazon, Apple, Microsoft, Google and Facebook.

In his testimony at the hearing about the deal, Cuban said that while radio and TV used to be the big competition for online streaming services, now its app-driven websites and services like Snapchat, He said Facebook is in the dominant content delivery position, saying it was taking over millennials and had become the major alternative to boredom, which used to be the province of TV and radio.

Public Knowledge president Gene Kimmelman countered that all those Web giants weren't charging $200 per month for those apps and that user-generated online content was not comparable to the expensively produced content from a Time Warner.

He also said those businesses are all dependent on the ISP gatekeepers, including AT&T.
