NEW YORK — Cyber Monday may be in danger of losing its online sales title.

The Monday after Thanksgiving is traditionally the busiest online shopping day of the year, but stores are releasing internet deals earlier, stretching them through the week, as well as making them available in stores. Shoppers looking for discounts spurred online sales on Black Friday to a new high.

During the holiday shopping weekend that kicks off on Thanksgiving and the day afterward known as Black Friday, more and more shoppers decide to skip the mayhem in stores and buy online. Consumers spent $3.34 billion shopping online on Friday, a 21.6 percent increase from the same day last year, according to Adobe Digital Insights, which tracks online retail transactions.

Online sales have also been stretching out more and more. Cartwheel, Target’s digital app, started offering holiday deals including 50 percent off one toy per day on Nov. 1. Amazon started offering 35 days of Black Friday deals on Nov. 16. And Walmart kicked off its Cyber Monday deals at 12:01 a.m. EST Friday for the first time as it aimed to grab customers ahead of its competitors.
