At one point in the mobile/social/video revolution, Twitter (TWTR) - Get Report was beating its peers to the punch, acquiring Vine and Periscope.

However, while Vine was once making quite an impact on the short, 6-second video world, that no longer appears to be the case. Twitter announced that it will shutter the service in the coming months.

That's bad news for a lot of Vine users, some of which had made quite a name for themselves on the platform.

Of course, Facebook's (FB) - Get Report efforts in video, along with Instagram's own ambitions, have likely put the squeeze on Vine. Couple Facebook's growth with Twitter's stagnant user growth and the latter had a recipe for disaster.

Throw in the fact that Snapchat has seemingly risen overnight with its picture- and video-taking capabilities and one can easily see why Vine has not only slipped in popularity, but has fallen so far it's being shut down.

It also goes to show how fast things can change in the consumer tech world when other companies are hot and have the growth, while others seemingly can't get out of their own way.

Shares of Twitter closed at $17.40 Thursday, up 0.6%.

"The early response to AirPods has been incredible. We don't believe in shipping a product before it's ready, and we need a little more time before AirPods are ready for our customers." This is what an Apple (AAPL) - Get Reportspokesperson toldTechCrunch in regards to the product's delay.

Hard to fault Apple here, especially considering that if a company like Samsung (SSNLF) had taken that sort of approach to its flammable battery situation, it would be doing a lot better at the moment.

In any regard, Apple is delaying the launch of its wireless headphone product, the Apple AirPods.

While certainly convenient, the device is expensive, standing at $159. For that kind of cash, consumers will want them to function without flaw, so it's important - even if inconvenient - that Apple gets it right from the start. Even if that means delaying the launch. 

It sounds like it shouldn't take too long though, which will be important for the company when it comes to the holidays.

Shares of Apple closed at $114.48 Thursday, down 1%. 

At one point, Groupon (GRPN) - Get Report rival LivingSocial was valued at $6 billion. That was back in the 2011 during a funding round, but my have the times changed. LivingSocial, which is backed by Amazon (AMZN) - Get Report , cut half of its staff about six months ago, and Groupon figured now was the time swoop in.

Of course, the company made this public in the same announcement that it told investors its earnings results, which topped earnings per share and revenue expectations. While this typically would be a good thing for the stock, an undisclosed price for acquiring LivingSocial doesn't seem to be pleasing the Street. 

Groupon even boosted its full-year revenue guidance, but that doesn't seem to be helping the stock either. It also plans to exit 11 countries and instead focus on just 15 countries. If it's going for profitability, this move is likely a good idea.

Despite the stock's decline, shares are still up nearly 100% from its 52-week lows of $2.15 per share.

Shares of Groupon closed at $4.10 Thursday, down 22%.
