During a conference call with analysts yesterday, HBO chief exec Richard Plepler suggested that the new HBO Now streaming service could possibly include non-HBO TV and film programming in the future. According to The Hollywood Reporter, Plepler said “Warner and Turner could be involved.” When asked about plans for expanding, Plepler explained that additional deals are expected by the end of the year, while HBO and Amazon are “in discussions about the size and scope of our relationship.” Regarding HBO Now’s performance, the CEO is “clearly thrilled at early returns and also argues that it vindicates the position that having a streaming service takes nothing away from viewers watching HBO in more-traditional ways,” notes THR.
