Target, Inc.

One retailer was clearly in a league of its own when it came to social media dominance of Cyber Monday.

Cyber Monday 2015 will be a day for the retail record books, at least until next holiday season.

Consumer spending across digital channels showed significant year-over-year growth over this year's Thanksgiving weekend.

According to data from ComScore, desktop spending surpassed $1 billion on both Thanksgiving and Black Friday. Consumers sitting at desktop PCs spent a total of $1.1 billion, up 9% from $1.01 billion in 2014. On Black Friday, desktop spending grew 10% to $1.66 billion from $1.5 billion.

For the second time this year, Target’s e-commerce site crashed due to exceptionally high levels of activity related to a major sales promotion.

The Target site went down the morning of Cyber Monday, Nov. 30. According to reports, the crash was actually a controlled restriction of the site by Target in response to extremely heavy volumes of visitors looking for holiday bargains.

Huge numbers of shoppers feasted on deals over Thanksgiving weekend, but how and when Americans did so has forever changed, as online activity exceeded store visits.

Retailers such as Walmart, Target, Best Buy and Macy’s spoke of well executed promotional strategies that leveraged their physical and digital presence and those insights were validated by data from the National Retail Federation’s Thanksgiving Weekend Survey conducted by Prosper Insights & Analytics.

Early indicators point to retailers having an historically strong Cyber Monday.

According to the Adobe Digital Index, as of 10 a.m. ET on Monday, Nov. 30, Cyber Monday online sales had already reached $490 million. Considering Cyber Monday online sales in 2014 reached a total of around $2 billion, and early Cyber Monday sales were tracking ahead of the prior year by 14%, this is a very possible start to a record-breaking day.
