Walt Disney struck a deal to buy Twenty-First Century Fox's assets for $52.4 billion in stock.
Fox rose 4.12 percent and Disney 2.2 percent, boosting the consumer discretionary sector by 0.5 percent. Other media stocks Netflix and Comcast were also higher.
Gains in technology stocks Alphabet and Facebook lifted the Nasdaq up 0.15 percent to 6,886.32.
Healthcare stocks were the biggest laggards, led by a 0.7 percent fall in Johnson & Johnson and 1.3 percent fall in AbbVie.
The Dow Jones Industrial Average was up 0.04 percent at 24,594.28, while the S&P 500 was down 0.02 percent, at 2,662.32.

The Fed on Wednesday raised interest rate by a quarter-percentage-point for the third time in 2017 and raised its 2018 economic growth forecast to 2.5 percent from 2.1 percent.
"Talks on tax reforms and the Fed announcement brings confidence in the fact that the economy is still moving in a positive and sustained fashion," said Paul Springmeyer, investment managing director at U.S. Bank Private Wealth Management.
"You've seen some M&A activity hit the screens that is driving some interest as well - that's a three-legged soul that's moving the market."
Growth outlook was also bolstered by data that showed a better-than-expected increase in U.S. retail sales in November.
The number of Americans filing for unemployment benefits fell to near a 44-1/2-year low last week.
