Your options for streaming services are only growing.

Part of the reason why $Netflix (NFLX.US)$ remains the champ isn't just the massive catalog and first-mover status (though both help). It also is frequently the best at rolling out new features. It offers mobile downloads and has been releasing its originals in 4K HDR for years (though you need its priciest Premium plan to watch in the higher quality). Netflix also benefits from having its app available on nearly every smart TV and streaming platform you could think of.

$Disney (DIS.US)$ Plus, however, is right on the tail of the current streaming king. The Mouse House's streamer has mobile downloads, a wide collection of 4K HDR content, allows for more people to watch and does so for an $8-per-month price that is cheaper than Netflix's most affordable non-HD plan. While its content library remains more family friendly in the US, those looking for anything Disney/Marvel/Lucasfilm/Pixar (a not-small net) will be very happy with Disney Plus.

$AT&T (T.US)$ HBO Max got off to a rocky start, lacking features like 4K HDR, mobile downloads or even apps for $Roku Inc (ROKU.US)$ or $Amazon (AMZN.US)$ Fire TV, but with time it has begun to find its footing. Major releases like the 2021 Warner Bros. theatrical slate and Zack Snyder's Justice League will stream in 4K HDR, the mobile app allows for downloads and apps are finally available for all major TV platforms. It has yet to release a "Max Original" to match the success of hits like Netflix's The Queen's Gambit or Disney's The Mandalorian, but HBO Max does have a strong library offering everything from Friends and Game of Thrones to Sesame Street and Looney Tunes.

Like HBO Max, Peacock got off to a slow start but has improved in recent months. In June it finally added an app for $Amazon (AMZN.US)$ Fire TV to round out its presence on all major platforms, and it even has 4K HDR on some titles. Mobile downloads are also present, and the additions of The Office, Modern Family and the WWE Network are sure to be welcome boosts for its otherwise still lacking library. It does, however, get points for being the only service with a free offering.

$Viacom-B (VIAB.US)$ Paramount Plus, the new name for CBS All Access, is among the oldest in this group, and parent ViacomCBS is hoping the rebrand will give it fresh life to compete with the others. It already has apps on all the major services and offers mobile downloads plus 4K HDR for some titles. The home for Star Trek and SpongeBob -- plus local CBS streams -- makes it an interesting option, but it will need more to rival the others. New shows announced for the service include Halo, Yellowstone spinoff 6666 and the iCarly revival.

$Discovery-A (DISCA.US)$ Discovery Plus is the other major new player. It has apps on most platforms, but not all, and some 4K HDR content. It does not, however, have mobile downloads and its content library lacks the mainstream hits offered by all the others. That said, if you're a fan of Pawn Stars, House Hunters or Cake Wars it is the option for you.
