In today’s update of technology news: U.S. economy getting less entrepreneurial? Tumblr to put ads on its blogs. Argos Therapeutics shares sink after stock sale announcement, Citrix talks ShareFile.

The U.S. economy has been getting less entrepreneurial for decades, as startups fell from 16.5 percent of all firms to 8 percent from 1977 to 2013, according to The Economic Innovation Group.

The decline touched all sectors, including tech. Startup activity has also become more concentrated in a few super performing geographic areas. Half the national increase in businesses from 2010 to 2014 happened in just four states –California, Florida, New York, and Texas.

We wonder if these statistics include the recovery of the last few years. Certainly North Carolina, particularly in the Triangle, has seen a significant increase in startup activity, though the report does not touch upon this. For the full story see:

Tumblr said this week that it will roll-out ads across its blogs to increase revenue on the Yahoo-owned site. Eventually, Tumblr says, it will share revenue with its bloggers, but not initially.

It said users will be able to turn off the ads in settings if they are uncomfortable with them.

Yahoo bought Tumblr for $1.1 billion in 2013 but has struggled to make money. Yahoo wrote down the value of Tumblr earlier this year b y $230 million.
