From live streaming to ad blocking, OTT in tumult in 2015 - Year in Review

For OTT, a disruptive year brought a few surprises but even more questions.

There's a very good chance that the video industry is tiring of hearing the word "disruptive." But that's a factor we saw all year in over-the-top video as a number of trends that analysts predicted would happen, came to fruition.

For example, we saw major broadcasters, networks and cable operators step away from the spectators' area and move into the streaming market -- some tentatively, others going all-in with SVOD (subscription video on demand) or AVOD (ad-supported video on demand) plays.

We saw advertising go through a tremendous change in terms of technologies used and in the market segments on which it focused -- as ad buyers began to allocate a greater part of their budgets to online video.

And we saw a huge amount of content being produced and offered to the public through a variety of distributors, from broadcasters to SVOD players and even in theaters with Netflix's (NASDAQ: NFLX) release of its first feature film, Beasts of No Nation.

It's been an interesting year across the board, and knowing that many of these trends were going to happen didn't make it less interesting. The early results from some of the new strategies being interesting, however, does raise the question of how new services and partnerships will fare in 2016.

Let's take a look at five of the top trending topics in the online video space in 2015. These are events that we saw as significant and that will continue to have an effect well into next year and beyond.
