Comcast Corporation (NASDAQ: CMCSA) is an American telecommunications and media conglomerate. It is the world's biggest entertainment company. In 2017, Comcast reported nearly $84.5 billion in revenue. Comcast has a market cap of about $161.5 billion as of July 19, 2018.

In June 2018, Comcast announced a $65 billion cash offer for certain Twenty-First Century Fox (FOXA) assets, $13 billion higher than Walt Disney's (DIS) offer of $52 billion. Last year, the company made an unsuccessful attempt to acquire Fox and lost out to Disney.

On July 19, 2018, Comcast ended its pursuit of Twenty-First Century Fox entertainment assets, setting the stage for Disney to acquire critical pieces of the media empire.

The company announced that it will now focus on European pay-TV giant Sky PLC. Fox already owns 39% of Sky and is vying to consolidate ownership. (See also: Why Comcast's Sky Bid Could Hurt)
