The television industry is currently facing a tough issue on finding long-term solutions to stay relevant in a dramatically shifting landscape. That's why, television's executives, producers and celebrities converged at the biannual Television Critics Association (TCA) press tour in Los Angeles this winter.

At the TCA press tour, networks' top bosses announced their current hit programming as well as their upcoming shows and plans. The event was also attended by hundreds of critics and reporters from all over the United States, who either celebrated or grilled the networks depending on their current status.

Aside from sharing their plans, certain themes and patterns also emerged. And here are 5 significant ways the TV industry will change this 2016.

1. More diversity is gradually coming to TV.

Over the years, TV networks and producers have promised to create more diverse programming. As a matter of fact, ABC took the lead with shows including "Blackish," "Fresh Off the Boat," "Scandal" and "How to Get Away with Murder." And the next star of the network's "The Bachelorette" won't be white, Business Insider noted.

Now, NBC has followed ABC's footsteps by launching the shows "Superstore" and "Shades of Blue," which feature Latina actresses America Ferrera and Jennifer Lopez, respectively. New CBS Entertainment President Glenn Geller, on the other hand, defended his network from claims that it isn't diverse, saying it fell into the LGBT category.

2. Live audience ratings are no longer the standard criterion.

The TV industry has always been dependent on ratings. Unfortunately, the old model of counting live viewers wasn't an accurate method to assess TV viewership. And Fox, the first network to end the reporting of its live ratings, explained that show renewal or cancellation decisions are not based on live ratings anymore.

3. Music is the future ratings' money-spinner.

Musical shows are currently on the rise and Fox has recently joined the musical trend with "Grease Live." And during the TCA press tour, NBC announced that they're closing a deal for "Hairspray." While cable and streaming also got into the trend, particularly with Showtime's "Roadies," HBO's "Vinyl and Amazon's "Mozart in the Jungle," which recently won a Golden Globe.

"One of the things we love about the shows is that the music makes the show feel very contemporary and kind of very exciting," Fox's CEO Gary Walden said of musical shows. "It gives it an element, a feeling almost of it being live."

4. Advertisement reductions are a must.

In order to entice and keep viewers, AdWeek has learned that reducing "overstuffed" ad load is a lod first step. In fact, Turner Entertainment chief creative officer and TNT/TBS president Kevin Reilly said that fewer, more effective ads are essential to "create a better viewing experience."

"TV is the best advertising delivery mechanism ever invented," Reilly said. "It's unparalleled for building brands and moving consumers, but we have overstuffed the bird and diluted the effectiveness of ads."

5. Eliminate the ads to make a series premiere stand out.

Advertisement reductions seemed to be not enough and some networks have opted to eliminate them to make their series premieres stand out.

"In today's competitive landscape, we felt it was important for viewers to get as pure and as uninterrupted an introduction to these worlds as possible," WGN America and Tribune Studios GM and president Matt Cherniss said.
