HBO Max shows growth despite industry slowdown

WarnerMedia's HBO Max streaming service gained subscribers over the holidays, defying the slowing pace of growth of some competing services, with lineup that included the rebirth of its popular "Sex and the City" series and new films such as "The Matrix"Resurrections.

HBO ended the year with 73.8 million subscribers to its streaming service and its eponymous cable network, up from 69.4 million in September. 

Those gains, coupled with the addition of nearly 900,0000 monthly paid phone subscribers, pushed the stock up 3% to $ 26.46. in the midday exchanges. 

“I think the  streaming service's cap is much higher than what we've seen to date,”  WarnerMedia CEO Jason Kilar said in an interview. 

“This will quickly become a three-way race for storytelling companies.


HBO Max still has a long way to go to capture market leader Netflix Inc, with  214 million subscribers, and Walt Disney Co (DIS.N) Disney +, with 118 million. Disney's growth slowed  in the company's fiscal fourth quarter, prompting a banker to downgrade the stock. Disney + added just 2.1 million in the October quarter. Netflix, which slowed sharply in the first half of 2021, saw its subscriptions increase in October, adding 4.4 million during the quarter, driven by the global sensation “Squid Game".

 WarnerMedia's HBO Max logged gains as it expanded the server reach from a single market, the United States, to 46 countries. Kilar said global expansion will continue this year,  eventually targeting 190 countries. 

AT&T (T.N) announced last May that it would split its WarnerMedia unit and merge it with Discovery (DISCA.O). The deal is expected to be finalized in the middle of this year.

NullPointerException in Java: Causes and Ways to Avoid It

NullPointerException: The Most Common Exception

NullPointerException (NPE) is the most common exception in Java. The cause of this exception is known but looks like that in most cases developers prefer to ignore it and don't take any action. I personally expect that reasons for such behavior are the following: 

  • Most of the developers don't see any problem here and recognize all NPE exceptions as the developer's fault. 
  • Developers who are aware of this design problem don't know how to fix it. 

In this article, I'll explain what is the root of this problem and provide ways to fix that problem.
