The best science-related content from 2018 is coming out of the most popular channels and has more than doubled in viewership in the past year.

That includes a whopping 88 percent increase in Discovery Channel and Discovery, plus a whopping 67 percent increase on TBS.

The network’s most popular programming has also grown in the same time period.

Discovery, Discovery Now, HGTV, Science, and Discovery Health all have more than tripled in viewership.

The Discovery channel has the most overall viewers, but Discovery is also the most influential, with almost half the viewers tuning in to the channel on average.

And Discovery’s top channels (TBS, HGG, and Scientific Channel) all have higher viewership than Discovery.

But there’s still plenty of room for growth.

In fact, Discovery, HG, and Science are all up 13 percent in viewership compared to 2017, while Discovery’s Top 3 channels (Science, Discovery and TBS) are up just 1 percent.

In other words, Discovery has a lot to live up to.

And it’s showing signs of growing.

For one, it has a larger audience than most other channels, with more than 6 million more viewers tuning into Discovery this year compared to last year.

Discovery has also shown a consistent trend of growing its audience.

Discovery’s audience increased 13 percent from last year, reaching a record high of nearly 1.2 billion viewers.

Discovery now has the second-largest audience among the top 5 cable networks, behind only TBS, with an average audience of 3.4 million.

The other two networks, Fox and CBS, are also at double-digit numbers.

In 2018, Discovery had the fourth-highest audience among all the networks, with 3.2 million viewers.

The rest of the networks have a combined audience of 1.1 million.

Discovery is the only network to have a positive audience in 2018.

Its audience is up almost 30 percent over 2017, and it has more viewers than the top networks combined.

And this is just the beginning.

Discovery says it is working to improve its overall customer experience, particularly with the arrival of new Discovery branded apps and the new Discovery Health app.

But that isn’t going to be easy.

In a recent report, Discovery predicted that it would lose a third of its total subscriber base by 2021.

That will only accelerate as Discovery grows its subscriber base.

That means it’s going to need to figure out how to do better in new niches.

And the challenge isn’t just finding new ways to reach more people, Discovery is going to have to figure up ways to get those people to watch it.

That could be as simple as making it more accessible and accessible to all.

That’s something Discovery will have to decide on when it releases its 2018 earnings report.

If it does it will have a lot of explaining to do.
