Samsung (SSNLF) introduced several new products at its Samsung Unpacked event in New York Tuesday. Leading the charge was the company's Note 7 smartphone, popularly known as the "phablet," as well as an upgraded virtual reality headset.

The company's new smartphone, referred to as a phablet because of its size (phone + tablet = phablet) will come equipped with a stylus and feature both finger print and retina scanning capabilities. Pretty hot stuff.

But Samsung is also keeping its commitment to virtual reality, with its new headset. The new Gear VR will still cost $99 - a very compelling price point compared to its competitors like HTC's Vive and the Oculus Rift.

It will also boast a new touchpad and slightly wider field of view.

Samsung already provides a compelling price point for its headset, but hopefully over time the pricing in the industry will come down, allowing for a wider adoption of the technology among consumers. The Gear VR will of course be compatible with the new Note 7 smartphone.

Although LinkedIn (LNKD) has been acquired by Microsoft (MSFT - Get Report) for $26.2 billion, it hasn't stopped the professional networking platform from making moves.

A few weeks ago, the company announced it will acquire PointDrive, which LinkedIn was actually a customer of before the acquisition. This time, the company isn't turning to M&A, but instead video.

Facebook (FB - Get Report) has talked about how important video is today and how much more important it will be going forward. LinkedIn must agree. It's invited 500 LinkedIn "Influencers" to post short videos responding to questions from the community.

The Q&A-type format may be just a stepping stone, but the company is hoping that these Influencers, people who have a lot of followers and regularly post to LinkedIn, will be able to spur increased engagement among users.

Given that this is just a starting point for the company, I would look for LinkedIn to keep developing this trend towards video and expanding in the future.

Shares of LinkedIn closed at $192.52 Tuesday, down 0.2%.

Twitter (TWTR - Get Report) Moments is a feature the company added to the platform in hopes of spurring increased engagement among its user base. The function, generally speaking, updates throughout the day with new content ranging from world news, sports, humor and several others topics.

Users have to keep on top of Moments if they want to see them, before the topic shifts to something new. Well, that will be a bit different for the Summer Olympic games.

The microblogging company plans to use Olympics-related Moments for weeks at a time, allowing users more time to check out what's going on down in Rio, as well as have a point of reference if they want to go back and check a specific event or tweet.

The company is also rolling out a number of different emojis -- 207 to be exact -- for each team at the Olympics. When users hashtag the three-letter code for certain countries, a flag emoji will appear. (Example: #USA will pull up an American flag).

Twitter also has a number of different hashtags set for the #Olympics.

Previous events, like the Super Bowl and World Cup generally work well for Twitter. But with streaming deals already in place for this year's games with platforms like Facebook, Instagram and Snapchat, perhaps Twitter won't be as dominate as usual. We will see.

Shares of Twitter closed at $16.43 Tuesday, down 1.3%.
