ComScore said 50 million Americans visited online retail sites on Black Friday, up 35 percent from a year ago. Each of the top five retail sites reported double-digit gains in visitors, in percentage terms, led by top retail site Amazon. Walmart ranked second, followed by Best Buy, Target and Apple.
Next up is Cyber Monday, when many online retailers run promotions for the first business day of the week following Thanksgiving. Cyber Monday sales topped $1 billion last year, making it the heaviest day of online spending ever. ComScore's Fulgoni expects another record will be set this year.
