It's a big day for "ThIs Is Us" — NBC has renewed the hit freshman for two more seasons.

The network made the announcement at its panel at the Television Critics Association press tour. Seasons 2 and 3 will both be at least 18 episodes long.

The renewal is no surprise, since "This Is Us" has been a huge success for NBC. It is the top new network series of the season, averaging nearly 10 million viewers and a high 2.6 rating in the coveted 18-49 demographic in live plus same day ratings. The show also received a Golden Globe nomination for best drama, NBC's first in a decade.

"We all got our wish that this is a hit show," said NBC Entertainment president Jennifer Salke. "'This Is Us' is as good as anything we've ever had, we're thrilled to renew it for two seasons and there's no doubt it will have a long life on NBC. On behalf of everyone at NBC, we're grateful for the artistry of the cast, crew, and producers assembled by our gifted creator, Dan Fogelman. In a world where there are literally hundreds of television dramas, we're proud to have one of the very best that is also one of the highest-rated."
