I don’t have live access right now to pull the latest broadcast details. I can share a quick guide on how to find the most up-to-date options, and give you a few typical platforms that commonly carry the game.

Where to watch typically

• National TV: NBA games between the 76ers and Celtics are often shown on ESPN, ABC, TNT, or NBC Sports networks depending on the schedule and region.
• Local/National streaming: Regional sports networks (RSNs) like NBC Sports Philadelphia or NBC Sports Boston may carry the game for local viewers, with streaming options through their apps or through a service like NBC Sports Live, depending on blackout rules.
• National streaming: If the game is on a national broadcast, you can usually stream it via the network’s official app (e.g., ESPN+, ABC via Hulu/Disney Bundle, TNT/TBS via Sling TV or similar), subject to regional rights and authentication.
• League Pass: The NBA League Pass typically offers live streams for out-of-market games and sometimes replays for in-market games.

How to verify for today

• Check the official NBA schedule page for the Celtics and 76ers for today’s game. It lists TV channel and start time.
• Visit the teams’ official sites or social accounts; they often post broadcast details.
• If you have a streaming service you already use, search for the game in its live sports section and check regional availability.

If you’d like, tell me your current city and which streaming services you have access to, and I can tailor a precise set of viewing options and potential login requirements. I can also provide step-by-step instructions to verify in real time.
