CBS Inc. (CBS) has become the first U.S. broadcast network to step into the Internet-only trend, just a day after premium-network HBO announced a cable-free service coming in 2015.

Named CBS All Access, the new service will offer most of CBS' TV collection, including more than 5,000 episodes of popular shows like Star Trek, The Big Bang Theory and MacGyver. One highlighted show not coming to CBS All Access is the NFL games, at least on launch.

CBS All Access will cost $5.99 per month, the same as Netflix. It's still unknown how HBO will charge for its streaming service, but it's expected to be at about the same price or $1 less to be competitive with Netflix (NFLX) and  Amazon's (AMZN) Amazon Instant Video.

One difference in CBS All Access is it will only be available to 14 markets in the U.S. at its launch, including New York, Los Angeles, Chicago, Philadelphia, Dallas and San Francisco. HBO is interested in getting their online service out to different countries in order to maximize potential revenue.

It does appear to be a quick move by CBS to get into the industry before any other cable services start cutting the cord in favor of an Internet-only streaming solution.

Industry watchers are waiting to see what other cable and satellite networks want to move to an Internet-only service. It's likely a lot more networks looking to make a service before the end of 2014.

These media companies still need to compete against Netflix and other services, but now that CBS is in the mix, it could turn into subscribing to multiple streaming services, which would cost the same as a cable TV subscription.
