Cynthia Littleton Business Editor As the fourth-quarter earnings cycle for Big Media closes today with Warner Bros. Discovery results after the market close, Wall Street will be eagerly looking for green shoots to confirm that the worst is truly over for the newly minted conglomerate. Warner Bros. Discovery shares have been gaining slowly but steadily since the beginning of this year as Team Zaslav hammers the point to investors that the worst of its integration and restructuring pain is behind them. WBD CEO David Zaslav has been ahead of the curve in preaching a return to the business fundamentals that have powered Hollywood for more than a half-century. Disney and Paramount Global delivered results earlier this month that came with sober warnings about streaming losses hitting a peak this year. Zaslav and WBD chief financial officer Gunnar Wiedenfels have promised analysts that the heaviest gusher of investment in HBO Max came in 2022 and that they are now on the path to taking the streamer to the promised land — profitablity — next year.
