It’s been a roller coaster ride in this week in tech. Twitter flies high with its IPO while Blackberry scrambles for options. Google launches a potentially game-changing product, while Blockbuster says goodbye to retail.

Twitter IPOs on Wall Street

The blue bird soared in its IPO yesterday. The initial offering price was $26 per share, the first trade was made at $45.10, and trading ended at $44.90 per share, for a 73% increase. Originally valued at $18.1 billion, Twitter is now worth over $31 billion.

Google Helpouts Launches

Google launched a new product called Helpouts, which allows users to access real-time advice from experts via video on a number of subjects, such as fitness, home improvement, and even healthcare. Providers are able to set their own prices, with Google taking a 20% cut of revenues.

It’s going to change the way large corporations provide customer service, as well.

Dish Network, Blockbuster’s parent company, announced that they’re shuttering its last remaining stores but will maintain the brand name as they expand digital offerings.

Netflix has won.
