The Interview was streamed more than 2m times in the first 4 days

"According to figures released by Sony Pictures, in its first four days of release, controversial comedy The Interview was “rented or purchased online more than 2 million times” between December 24th, when it was released, and December 27th. “Total consumer spending through Saturday for The Interview online is over $15 million,” Sony said in a statement.
The totals do not include December 28th, when co-stars Seth Rogen and James Franco and co-director Evan Goldberg held a live-tweet session to further promote online streams of the movie. Online revenue far exceeds that from theatrical release, despite sold-out showings in a limited number of theatres across the country. The Interview is expected to make about $2.8 million at the 331 independently-owned theatres that have been showing it since Christmas Day."
